Can't run CB on Ubuntu

[Kalith]

Very strange problem...
I installed Ubuntu recently to try my project on Linux, and everything was working fine.
Until tonight : CB (latest nighty) refuses to launch, for no apparent reason.
No matter if I run it directly or by executing a .workspace or a .cbp.

I've tried :

• re-installing
• complete uninstall + install
• removing the content of /home/<my home>/.codeblocks
• installing another package (not using the depot)

None of the above changed a thing.
Maybe it is crashing silently (apparently like everything on Ubuntu), but I don't know where I could find the crash report.

The only thing I changed was unplugging an USB key, but I never used it directly with CB (I used it to transfer files between Ubuntu and Windows).

Hum... okay nevermind.
I tried running CB with the console, and it showed that it was missing a *.so.
I don't know if it was the original problem, but I downloaded it and now it works.
Even stranger
