[Merge] lp:~j-corwin/openlp/bug-1041366-jc into lp:openlp
Jonathan Corwin has proposed merging lp:~j-corwin/openlp/bug-1041366-jc into lp:openlp.
Requested reviews:
Tim Bentley (trb143)
For more details, see:
https://code.launchpad.net/~j-corwin/openlp/bug-1041366-jc/+merge/121477
This includes Raoul's code to fix the display area for bug 1041366 but it includes some extra code to prevent the problem with bug 1016843 being reintroduced when OpenLP crashes on Windows when editing a theme whilst many items are in the service.
** This is attempt number two. I discovered my first stab at this only fixed the problem from the PyCharm debugger but not the commandline. This attempt appears to prevent the crash from the commandline too (today).
