This bug has happened to me yesterday when I upgraded gitk from 1:2.5.3-1 to 1:2.6.1-1
My system is in spanish: from aptitude.log: [ACTUALIZAR] git:i386 1:2.5.3-1 -> 1:2.6.1-1 [ACTUALIZAR] git-core:i386 1:2.5.3-1 -> 1:2.6.1-1 [ACTUALIZAR] git-doc:i386 1:2.5.3-1 -> 1:2.6.1-1 [ACTUALIZAR] git-gui:i386 1:2.5.3-1 -> 1:2.6.1-1 [ACTUALIZAR] git-man:i386 1:2.5.3-1 -> 1:2.6.1-1 [ACTUALIZAR] git-svn:i386 1:2.5.3-1 -> 1:2.6.1-1 [ACTUALIZAR] gitk:i386 1:2.5.3-1 -> 1:2.6.1-1 $ gitk -- view_reservada.qs Error in startup script: bad menu entry index "Modificar vista..." while executing ".bar.view entryconf [mca "Edit view..."] -state normal" invoked from within "if {$cmdline_files ne {} || $revtreeargs ne {} || $revtreeargscmd ne {}} { # create a view for the files/dirs specified on the command line se..." (file "/usr/bin/gitk" line 12442) $ LANG=C; gitk -- view_reservada.qs (without visible error) Also, in my system, doing "gitk" without arguments works. But whenever i put one, i get the above error. Please note this package version is in unstable and testing.
