Doesn't look like it's related to bzr-svn to me. Reassigning to bzr.

[Robert Collins (lifeless)]

what happens if you just run 'bzr break-lock .' ?

[Zygmunt Krynicki (zyga)]

Nothing, the command finishes sucessfuly but commiting fails as before.

zyga@zyga:~/cond$ bzr break-lock
zyga@zyga:~/cond$ bzr ci -m "cond__log_signal defaults to stderr if no stream is supplied"
bzr: ERROR: Could not acquire lock LockDir(file:///home/zyga/cond/.bzr/repositor y/lock)

[Zygmunt Krynicki (zyga)]

Okay I resolved this issue
I had to manually create the directory .bzr/repozitory/lock (same with branch and checkout)

I think bzr should check that condition and act appropriatly

[John A Meinel (jameinel)]

The associated branch has a fix for this. It may make it into 0.10, it should make it into 0.11.

[John A Meinel (jameinel)]

merged into 0.10
