Hello,
My usual problem: I have a threaded gtk app which doesn't thread.
Here is what it should do:
The user selects elements in the list and then presses a button. For
each selected element, a new thread should be started to do some
operations and update the clist.
Here is a sample output:
Begin doStartThreads
[1, 0]
Starting thread for row 0
Starting thread for row 1
End doStartThreads
This means that the function is called, the first two rows are selected
and that the threads have been started. The thread should print
"updateRow %d" % row but that doesn't happen.
The source is attached. My system is SuSE 6.0 (glibc based), thread
support has been compiled in every part (ie. python, glib, gtk+ and
gnome-libs).
