Fascinating. So //kalma/xxx/yyy is a depot hosted in a p4d that runs on your local box, but //xxx/yyy is the depot name hosted in the company's p4d?

I'm completely confused that //kalma/xxx/yyy even appeard to work at all. Will be interested to see your P4PORT setting when using that repo.

Ooh. You're using the shiny new "streams" feature in p4, I think. Can you play with "p4 stream" to see if one is defined on //xxx or //xxx/yyy?.

Could be that the work-around is to use "p4 client" to set the "Stream" field. This p4 forum post talks about using "p4 client -s -S ...".

http://forums.perforce.com/index.php?/topic/1139-seeding-streams-from-existing-depots-failed/

which is explained at the bottom of this section:

http://www.perforce.com/perforce/doc.current/manuals/p4guide/06_codemgmt.html#1066766

If you can help us understand the problem a bit better, a reasonable fix might be to detect this situation in git-p4 and at least explain how to fix it. Since git-p4 does not create the client used for submit, we don't have much control over its settings.
