[SRCTREE-1983] SourceTree locks up ("spinning rainbow cursor") when VoiceOver is on

Type: Bug
Resolution: Unresolved
Priority: High
Fix Version/s: None
Affects Version/s: 1.7.4.1
Component/s: General
Labels:
None
Environment:

MacOS X 10.9.0
Mac Pro (mid-2010), and MacBook Pro 15" Retina

Symptom Severity:
Severity 1 - Critical

Whenever I turn on VoiceOver while SourceTree is running, SourceTree goes into an endless loop. The spinning rainbow cursor appears and my only option is to force-quit the app.

I've been working on accessibility support in my application, so I've been using VO a lot. I've been noticing that SourceTree has been locking up like this for a while and it has been driving me absolutely nuts.

But I didn't put my finger on VO as the culprit until I happened to look at a stack trace showing where it was hung.

Once I saw that accessibility related stuff on the stack, I tried reproducing the problem by turning on VO and it instantly spinning-rainbow-cursor-locks SourceTree every time.

Hey Bobby,

Yes I've just been testing this and it locks up the moment an NSTask instance is executed which is very strange. I'd also suggest this is an Apple bug as I can't dig inside of that, and there's no environmental reason otherwise that this shouldn't work.

We've got a link to that rdar anyway, so once there's some change in that we can address the issue in SourceTree.

Cheers
