git gui often freezes on Ubuntu 18.04. I can reproduce the problem by
launching the gui several times. If I press the "ctrl" key then the
gui becomes visible.

Collected information.

Hi Peter,

git-gui is written in Tcl. So while strace output might give some clues, 
it is not as helpful as I'd hope. And anyway, I'm afraid I just don't 
have the bandwidth to look through it and figure out what's going on.

If you could try the latest master [0], it would be nice. The build is 
pretty simple and quick. Any hints more specific than "something 
crashes" would be much more helpful in figuring out what's going wrong.

Pratyush,

The program freeze before the main window appears.
As far as I can see from the strace log "tcl" is waiting for something
to happen.
I think "tcl" is waiting for the output from a git command.

If the strace log does not give you any useful information, what do you suggest
I do to track the bug down? Has git-gui got any logging build in that I can
activate via an option e.g "-debug" or by setting an environment variable?

If not can you suggest anything that would be useful?

I installed 18.04 on my laptop, and the bug also showed up here.
The machines have very little in common, except that they
both have a SSD disk.

Peter

git gui often freezes on Ubuntu 18.04. I can reproduce the problem by
launching the gui several times. If I press the "ctrl" key then the
gui becomes visible.

Collected information.
