In "M-x gdb", filename completion with mouse erases the default gdb command

[Gallagher, Kevin]

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-gnu-emacs@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:


After entering "M-x gdb", the input line in the minibuffer is seeded
with
the default gdb command followd by the previously debugged executable.
I erased the previous filename and then added a partial filename,
pressed
TAB, and the possible completions were displayed, as expected.  After
selecting a filename with the mouse, the default gdb command was
entirely erased, leaving only the selected filename at the prompt in the
minibuffer. 


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
/users/gallagk/usr/local/share/emacs/22.1/etc/DEBUG for instructions.
