Comment 0 for bug 93609

After mucking around a bit with lp://, I came across these errors for things that I might have expected to work.

jml@rhino:~$ bzr branch lp:no-such-project
bzr: ERROR: Not a branch: http://code.launchpad.net/no-such-project/
jml@rhino:~$ bzr branch lp://subunit
bzr: ERROR: Invalid url supplied to transport: 'lp://subunit'
jml@rhino:~$ bzr branch lp:subunit/fix-stdout
bzr: ERROR: Not a branch: http://code.launchpad.net/subunit/fix-stdout/
jml@rhino:~$ bzr branch lp:~exarkun/subunit/fix-stdout
bzr: ERROR: Not a branch: http://code.launchpad.net/~exarkun/subunit/fix-stdout/
jml@rhino:~/Code/Subunit/trunk$ bzr push lp:subunit/new-branch
bzr: ERROR: Transport operation not possible: http does not support mkdir()

These errors (particularly the last one) should be cleaned. The new errors messages should refer users to 'bzr help launchpad'.
