#89 Exception after commit from command-line ("formattedDescription")

Reported by Mark Birbeck / mark.birbeck, created 5 months ago, last edited unknown.

I had three windows open in Murky, each pointing to different repositories. In a terminal window I performed a commit, and immediately got an exception dialog, with the following message:

Uncaught exception: NSRangeException
Cannot remove an observer <NSKeyValueObservance 0x1444a00> for the key path "formattedDescription" from <HgUncommittedRevision 0x142ec50> because it is not registered as an observer.

Thanks!

→ Changed responsible from nobody to snej.

→ Changed status from new to open.

I can't reproduce this myself, but I think I've figured out what causes it, and put in a fix. (It's yet another KVO dependency tracking problem.) I've checked it in locally as r115:295c56fb3a4d , will push to the repo soon.
