bug#4868: 23.1; "No fileset is available here"
Tom Tromey
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.
Your bug report will be posted to the bug-gn...@gnu.org mailing list,
and to the gnu.emacs.bug news group.
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
I modified a file in a git-managed directory.
Then I typed `C-x v ='.
I got an error: "No fileset is available here".
However, if I switch to another buffer visiting a (modified) file in
that same directory, `C-x v =' works just fine.
If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
`bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/share/emacs/23.1/etc/DEBUG for instructions.

Is this file not registered with Git?
If yes, then that's the error it would get.
emacs-22 used to have a nicer looking error in that case: "File is not
under version control". Not sure why that check got removed, there's
nothing in the ChangeLog to explain it :-(

Looks fine to me.

Yeah, it turns out it is not.
I switched branches to a branch where this file did not exist, but
didn't remember that, and also didn't update TAGS. Whoops.
