Summary: Dragging unselected verse to bookmark panel ==> crash

Initial Comment:
Dragging an unselected verse to the bookmarks panel will lead to a segfault.  This did not occur in 2.0.

Message:
The fix (git commit) that Gary pointed to is a trivial one line change. 
Just a check for whether something is NULL before using it.

I'd try just patching the 4.5.2 sources to match that, and rebuild :)

Message:
Thanks!  Any idea of when 4.5.3 is scheduled to be released?  I've looked
around but found no release dates yet.  Perhaps I should just go to 4.5.0.

Message:
After a dialog with Qt people and supplying them a test program that also
crashed, they agreed that there was a bug in Qt 4.5.2, but that it had
already been fixed for the coming Qt 4.5.3. Here is a reference to the
change in Qt.

I switch from qt 4.5.2 to 4.5.0 on ubuntu 9.04. The crash went away.

Message:
I duplicated the problem in BT 2.2.beta1 with ubuntu and kubuntu 9.04. Both
had qt 4.5.2. A stack trace showed the problem deep into QtWebKit code.
Also, I tried this in OpenSuse 11.1 with qt 4.4.3 and it did not crash.

It appears that the problem is in the qt 4.5.2 library.
