This gives some clues, but sadly, not enough. There's too much that happens
between the messages
[DEBUG ] e2_combobox_set_active: 0
and
[DEBUG ] _e2_fileview_change_dir ends
I don't get the same crash here. So I've looked at and stepped through the
relevant code a bit, but can't see where a problem might be. And also, my code
is now a bit different from the last release.
Do you get a core-dump which can be opened with gdb to do a backtrace ?
Otherwise, must resort to trial and error, sprinkling more error-messages
around to find where the crash happens.
