Comment 4 for bug 144300

I am getting this error using both bzr 1.6b1 and bzr.dev revno:3493 when attempting to do 'bzr log -r branch:X'. Here is what I get:

cdb@tsunami ~/grub/repo/videotest $ ~/src/bzr/bzr.dev/bzr log -r branch:../upstream..
bzr: ERROR: bzrlib.errors.ReadOnlyError: A write attempt was made in a read only transaction on KnitPackRepository('file:///home/cdb/grub/repo/.bzr/repository/')
