Mario,

here are two of those.

The first: open a project, close one of the open files.

please observe the line
> gideon: No bookmarks in  - Deleting

# grep -r "No bookmarks in " *.cpp
parts/bookmarks/bookmarks_part.cpp  [...] << data->url.path() << [...]

I might expect the file '/home/franke/devel/zombie/src/zombie.c' between
those two whitespaces?!

Here another backtrace, after setting a bookmark in the file to close:
