git-gui doesn't display over ssh, gitk is ok

git-gui displays nothing when running it over ssh -X. gitk works fine, so this doesn't seem to be a problem with X-Windows or my ssh setup (other X apps are fine, too). I'm running 1.5.5.rc0 now, but this has been true since I began using git.

The only thing google gave me was something about running git-fetch from git-gui in msysGit, which I am not using.

Seen this before? Any ideas?

Thanks.

FWIW I'm using git-gui 1.5.4.1 without any hickup over SSH -X -Y. On the contrary gitk is causing problems because it loads the whole commit history in the window, and that takes a lot of time over the network.
