QListWidget->clear() segmentation fault
Message 1 in thread
Hello all!
I have following code:
if ( contactListTree->count() > 0)
contactListTree->clear();
where:
contactListTree = QLIstWidget;
But after I try to run it it segfaults. can anyone tell me why?

Not without some more information, we need a backtrace and a small
self-contained example that demonstrates the problem.
A wild guess would be that clear deletes the items, and one of the item
pointers was earlier deleted by you, without removing it from the
listview...

Is contactListTree a valid address?
