General MoBlock thread

[freedom]

Mobloquer stop working on me!..
Everything was OK... mobloquer was working perfectly but now I get
Segmentation fault on console when I started it. Does anyone have the same problem?
I cannot connect this Segmentation fault with anything I do recently... I only update packages regulary.
Tried to remove .config/mobloquer dir from my HOMEDIR but that doesn`t do the trick.
Any ideas?

[jre]

Sorry, no. You already did what I would have suggested (remove ~/.config/mobloquer). Perhaps reboot. You are the first and only who has reported this problem currently.
Can you post the complete console output?
What's your Ubuntu version?

[freedom]

OK... here is some details...
I installed from repo...

deb http://moblock-deb.sourceforge.net/debian intrepid main

so you see that I'm using Intrepid 8.10
Console output is rather poor... maybe there is option to increase verbosity?

dan@GX610:~$ mobloquer
** Warning: Prefered file "/usr/bin/kdesu" could not be found, using "/usr/bin/gksu" instead
Segmentation fault

moblock and moblock-control for itselfs works like a charm but mobloquer even purged and reinstalled, don't.

oh.. and here is line from dmesg output...

[25406.992283] mobloquer[14520]: segfault at 5b ip b7475c72 sp bfa3c610 error 6 in libQtCore.so.4.4.3[b73db000+225000]

[jre]

Unfortunately that's beyond my knowledge.

I assume /usr/bin/gksu exists and is executable!?

It also might be a bug in libqt-core. But I guess most mobloquer users do use Ubuntu intrepid, and I still haven't received other bug reports ...

For future reference please post

dpkg -l "libqt*"

. Do you remember if there was any update of libqt lately?

[freedom]

Yes, gksu exist, kdesu doesn't but there is kdesudo. Maybe you should use kdesudo for administrative privileges.
Here is the oputput of dpkg...

GX610:~$ dpkg -l "libqt*"

Well, maybe the problem is with latest libqt in KDE4 update... 4.2.1

[freedom]

NO. It is not KDE 4.2.1 update...
I have installed mobloquer on other machine and perform an update and everything worked fine... before and after update.
Strange thing that both machines have pretty much the same things installed and KDE4 as desktop environment but still on the first one mobloquer stops to work (and it has been worked for some time).

If anyone knows or maybe if developer of mobloquer read this...
Is there an option to have verbose output on errors rather than just "Segmentation fault" ?

[jre]

With the next release I will (try to) provide a mobloquer-dbg package. Then it will be possible to make a backtrace with dbg. I hope to do this this weekend...

[jurelex]

Hi all. I'm having the same problem...

I installed both moblock and mobloquer

sudo apt-get install moblock mobloquer

I tried uninstalling and reinstalling, also tried deleting the configuration file but I still have the same problem

~$ mobloquer
** Warning: Prefered file "/usr/bin/kdesu" could not be found, using "/usr/bin/gksu" instead 
Segmentation fault

Currently I have no clue what's going on.
But with the next update there will definitely be a mobloquer-dbg package. I've already tested it locally.
If your problems persist, you can make a backtrace with "gdb mobloquer", followed by "run" on the gdb prompt.

EDIT 1: I guess you are on intrepid, too?

EDIT 2: At least the dependencies of the new packages have changed:

mobloquer_0.6-1~pre3+intrepid_i386.deb:
Depends: libc6 (>= 2.1.3), libgcc1 (>= 1:4.1.1), libqtcore4 (>= 4.4.3), libqtgui4 (>= 4.4.3), libstdc++6 (>= 4.1.1), moblock, blockcontrol

I am a linux newbie and have had issues installing moblock, I followed the howto but after rebooting when I do:
