bash.exe: warning: could not find /tmp, please create!

[kasal]

Hello, I'd like to ask for help with the issue demonstrated below.
After some time of work (under windows 7, 64bit) we get this problem, git cannot start, as the "mount" is somehow borked. Reboot of the comp helps.
This happens to only one of the guys in our team (i.e., on his computer only).

My understanding is that the "msys gets borked somehow".
I also guess that it might be connected to the problem with "dll rebase".
Perhaps the user starts some application that somehow conflicts with msys. But I'm afraid he is not willing to spend time to localize the problem; he just reboots in that case.

Are my guesses right? Is there something I could do to remove the problem?

ERROR: HOME directory 'C:\Users\johndoe' doesn't exist!

This is an error which might be related to msysGit issue 108.
You might want to set the environment variable HOME explicitly.

Falling back to / (C:/Program Files (x86)/Git).

This is most likely caused by the lack of the environment variable TMPDIR or TEMPDIR (cannot remember which).
