bzr crashed when attempting to add directory containing an hg repository. ERROR: bzrlib.errors.ReadOnlyError

[Vernon Cole]

This is VERY low priority. The simple work-around is "don't DO that." However, the fix might be simple, or a more specific error message might be possible.

I added a NetBeans project tree to an existing bzr working directory by copying it there using "cp -r".
I must have triggered NetBeans built-in mercurial support on the project at some time. (I am learning Java for a college class -- and like Python better with every Java program I write.) The result was that inadvertently placed a mercurial tree inside my bazaar working set. When I attempted to "bzr add" the new directory, bazaar crashed.

I have the bzr-hg 0.2.0~bzr299-1 plugin installed. I don't know if the bug is in the plugin or in bzr itself. It's more important to me to have bzr-hg working on Windows than to have this fixed, so don't spend a lot of time on it.

Note: Removing .hg directory and .hgignore file completely fixes the problem.

This should eventually add the hg repository as a subrepository.

For the moment, however, it should not trigger a traceback but just print a normal error.
