Hi,
This may be of use somewhere, using current SVN I got the attached errors. Unfortunately Geany was covering the terminal so I didn't see when they occurred or I would have investigated a bit more. Files open were search.c, keyfile.c and editor.c.
At one point the sidebar was very slow to respond which might or might not be a hint.
Goes without saying I can't repeat. :-)
Cheers Lex
