Comment 1 for bug 594958

Ditto me. Have successfully merged patch into my trunk once previously, and a number of local feature branch merges as well.
Now patch command (not tried by me before) gives messages like;

Run command: bzr patch "C:/Documents and Settings/Bruce/My Documents/Bruce/Outdoor/Cave/Therion Data and Notes/th_RiwakaCaveSystemData/MikesS...
bzr: ERROR: Error invoking patch: No such file or directory

Run command: bzr patch ../MikesSwissMaidBranch-28.patch
bzr: ERROR: Error invoking patch: No such file or directory

and merge gives message like;

bzr: ERROR: exceptions.IndexError: list index out of range

That "/trunke']" at the end of one of the lines above perplexes me. The actual path ends like "/trunk"
All was working well for a while, and now we seem to be stuck.
