don't know what happend. All of a sudden I my programes crashes when I open the save/open dialog.
I get this error:

'geany: symbol lookup error: /usr/lib/libgtk-x11-2.0.so.0: undefined symbol: g_utf8_collate_key_for_filename

It is all my programmes that crashes.
I tried to install gtk and gtk+ again but nothing happend, I also tried replacing libgtk-x11-2.0.so.0
but still nothing. What is wrong?
