All of a sudden the log view in SourceTree no longer lists the files that were changed in each revision. This is happening on all repos (I have a couple dozen) and in all revisions. It just started after my last commit (which worked fine; I confirmed with the Hg command line tools).
Restarting the app didn't help, so I restarted my entire machine (MacBook Air 2012, OS X 10.8.4), which also didn't help. This has never happened before, but now I can't seem to fix it. I've verified that all my actual repos are fine, so it's definitely just a bug in SourceTree.
Pretty huge bug, though, as it makes the app pretty much completely unusable.
Couldn't find anything on Google or in a search here.
