gitk endless loop

This recipe sends gitk into an endless loop. In git.git do:

cd t # remove chmod a+x A near the end of the file sed -i 's/chmod/: chmod/' t3400-rebase.sh sh t3400-rebase.sh --debug cd trash\ directory.t3400-rebase/ gitk master modechange modechange@{1}

I briefly see the history chart, but the dot that should be modechange@{1} is missing. One automatically selected commit is shown in the diff section below. But then the commit list is cleared and gitk goes into an infinite loop.

Things work alright if either modechange@{1} is dropped, or the 'chmod' line is left unchanged, which is a bit strange.

This is with git version 1.6.1.2.390.gba743
