Hi

I've just had git-gui crash on me when I tried to enter the ~ (tilde) character on my Mac mini under OS X 10.6.8:

terminate called after throwing an instance of 'NSException'
error: git-gui died of signal 6

[sorry for wrapping]

I use the Swiss German keyboard layout where the tilde is a dead key on Fn+n (for entering the spanish ñ, I assume). Other dead keys like ¨, ´ and ` also cause git-gui to crash. It does not matter whether the dead key is the last one in the commit message or not.

Interestingly, the commit text was saved to .git/COMMIT_MSG in spite of the crash, so I didn't lose any of it.

I use the current git 1.7.9 installed via homebrew.

Thanks,
Beat Bolli

PS: Please CC me on replies, I'm not on the list. Thanks.

This doesn't look git-gui specific so you will likely get more results posting to the comp.lang.tcl newsgroup about this - or there is a mac-specific tcl/tk list someplace.

Not posessing a Mac I can't look into this at all - but an NSException -- that is a problem from the Tk to native layer.

OK, I'll try to find the appropriate group.

Thanks,
