I have a weird problem in TexMacs...

I create a new document, insert a title field, type "Frequenc" and TexMacs crashes! This happens EVERY time. I also tried typing something else, like "Report - Frequenc" but it always crashes when I hit the C. Doesn't happen for any other text except the word frequency, and also doesn't happen if I type it anywhere else - happens just in the title field.

Anyone know how to fix this?
Can anyone reproduce this problem?
TexMacs bugs list is like 3-4 years out of date and I can't find any link to create a bug report..
