jiggamam,
You have to try a few things...
First, your backtrace does not show the cause of the crash, it would be nice to know it (segfault? other signal?). Do you have these lines in your .gdbinit? You can enter them manually if you like, but it gives you more trouble and you will end forgetting it:
ha SIGPIPE nostop noprint pass
ha SIG32 nostop noprint pass
ha SIG33 nostop noprint pass
ha SIG34 nostop noprint pass
maybe, take a look at this, if you haven't already done so:
http://www.amule.org/wiki/index.php/BacktracesYour crash is inside libglib.I am using glib-1.2.10 here, maybe you are using an unstable version? Either try to upgrade or downgrade it to see if it changes something.
Also, I can see you are using wx-2.4 with gtk-1.2, which is fine, unless you have unicode enabled. If that is the case, build without unicode support.
I don't have the detais about your machine and your restrictions, but your current setup is almost obsolete because of wx-2.4.2, just use this if you have memory size constraints. The recommended setup these days is to use gtk-2 and wx-2.6.
If you are willing to recompile yourself, I suggest wx-cvs and aMule-cvs. If not, then it seems that there is no "good" wx debian package these days, wx-2.6.1 has some memory usage problems, wx-2.6.2 has a bug with locale, but if you use default locale or en_US, it will not show.
aMule CVS has KAD enabled.
Cheers!
