Cyberduck Bounty

Since I have included Uli Kusterer’s Crashreporter in Cyberduck, there have been many reports sent in. Some of them made me aware of problems and bugs got fixed. However, there are some crashes, I cannot track down:

This looks completly obscure to me. It might be some concurrency issue in the menu delegate code (e.g. in the BookmarkMenuDelegate (line 160), HistoryMenuDelegate (line 218) or RendezvousMenuDelegate (line 283) of CDMainController. Or not. It might be a completly different issue I am unaware of or it might be a bug I can’t even fix myself but is in closed code from Apple (I have filed radar://4784618). Any ‘diff’ sent to me resolving the crash gives a bounty (using Paypal) of 100$. You can check out the Cyberduck source code from the Subversion repository.
