Hi, Andre.

After a "ps -ef" I saw two instances of the script defined by GIT_PROXY_COMMAND. Strangely one of those instances was child of the other. A strace showed the scripts were blocked in a "waitpid(-1,". I've killed the child script and the git clone resumed the process.

I didn't understand why this blocking on git happened though. The creation of these two instances (one child of the other) was also strange.

Regards, Humberto

I'm also receiving these messages when trying to change branches:

doctorture:/opt/downloads/mvista/linux-mvista # git-checkout origin fatal: Untracked working tree file '.gitignore' would be overwritten by merge.

Perhaps I will need to download using git-clone again?

Thanks,
