Troubleshooting intermittent errors committing via QCT

[Sean]

I've raised this issue b4 on this list, without resolution.

I occasionally get the following errors when committing from QCT:
______________

Auto-detected Mercurial repository
Error code 255 not expected
Traceback (most recent call last):
  File "qctlib\gui_logic.pyc", line 788, in commitSelected
  File "qctlib\vcs\hg.pyc", line 521, in commitFiles
  File "qctlib\vcs\hg.pyc", line 129, in hgcmd
  File "qctlib\utils.pyc", line 170, in runProgramStderr
qctlib.utils.ProgramError: F:\APPS\mercurial\hg.EXE commit -l 
t:\temp\tmpug9mqk
[FILES]
______________

Despite the error, the commit succeeds, but post commit hooks fail.

The error is not reproducible and there does not seem to be any pattern 
that I can see.

I have tried, as suggested, to rollback the commit, then try it again 
from the cli with:

hg commit --debug -m "commit message" [FILES]

The cli commit invariably works without error.

I am running QCT 1.5 on windows xp, against Mercurial 1.0 (berkwood binary)

Any suggestions ?
