IndexError: array index out of range
cmdserver: process exited unexpectedly with code 255

Tried verifying (both local and remote repositories), but it does not find
anything suspicious:
% hg verify -v
repository uses revlog format 1
checking changesets
checking manifests
crosschecking files in changesets and manifests
checking files
checked 11 changesets with 16 changes to 7 files

Push goes correctly, because pull correctly shows phase public changed from
draft:
% hg pull --verbose "R:\Remote\Directory"
pulling from R:\Remote\Directory
searching for changes
no changes found
1 local changesets published

I can push second time instead of pull and shows there is nothing to push - it
also updates phases:
% hg push "R:\Remote\Directory"
pushing to R:\Remote\Directory
searching for changes
no changes found

Can i do anything to help find or fix issue?
