Severe symbol sigaction error on Koala (Synaptic crashes)

[sayyeah]

Hi all, after upgrading from 9.04 to 9.10, I cannot run the svn client and Synaptic manager. (possibly some other apps as well.)

First, I tried to update from svn repo using conventional commands:

$ svn co https://robotcub.svn.sourceforge.net/svnroot/robotcub/trunk/iCub

svn: relocation error: /usr/lib/libapr-1.so.0: symbol sigaction, version GLIBC_2.0 not defined in file libpthread.so.0 with link time reference


So after searching for libapr-1 on Synaptic, I found that there are libapr-1-dev and -dbg packages.
When I tried to install them, an error message appeared:


dpkg: relocation error: dpkg: symbol sigaction, version GLIBC_2.0 not defined in file libpthread.so.0 with link time reference

After this incidence, I cannot even run Synaptic manager at all now!
It only shows the following error message:



E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
E: _cache->open() failed, please report.


When I run as it says:


$ sudo dpkg --configure -a

Setting up man-db (2.5.6-2) ...
dpkg: relocation error: dpkg: symbol sigaction, version GLIBC_2.0 not defined in file libpthread.so.0 with link time reference
sayyeah@kyu-mobile:~/work/icub/icub_software$ /usr/bin/perl: relocation error: /usr/bin/perl: symbol sigaction, version GLIBC_2.0 not defined in file libpthread.so.0 with link time reference


Any hint please?

Well, 'sudo dpkg --configure -a' worked after two times of rebooting. Now svn and Synaptic are running ok but I really don't understand about this weird behavior.
