Inkscape doesn't open on ubuntu 12.04

inkscape keeps crashing while loading, and the error message doesn't give any hint.

Emergency save activated!
Emergency save completed. Inkscape will close now.
If you can reproduce this crash, please file a bug at www.inkscape.org
with a detailed description of the steps leading to the crash, so we can fix it.

The problem is that I substituted its icon in .icons. Then a conflict took place... Now, I've just undo that and inkscape return to work.
