[paragui-users] Still the problem with self modifying listboxes (return of the newbie question).

[Guillaume Schmid]

Hello,
I just updated my cvs branch (devel-1-0) and tried again my small image
viewer app and still have the same problem.

My problem was (and still is) that I have a listboxes that show a dir
list. If you click on a subdir, I want to update the list. I have to
destroy every item and re-fill le this with updated content.
I handle this task into the EventSelectItem of the listbox but a mutex
has been locked before calling this function on the selected item and
will be free after. Problem, sice I destroy the item, the event managing
code cannot free it: boom.

Alexander told me that he removed the offending code but I still have
the problem.
Did I check out the right branch ? 

Thank you for your attention.

Here is my stack trace:
