Completed git-bisect twice, getting roughly the same results:

    828a84ba3341d4b7a84292d8b9002a8095dd2382 is the first bad commit

        Add version command to show git-annex version as well as repository version information.

contents of final refs/bisect:

\"roughly\" because second bisect gave two commits as a result, failing to build one of them (missing .o file on link, guess it's because of -j4 and bad deps in that version's build system):

    There are only 'skip'ped commits left to test.
    The first bad commit could be any of:
    828a84ba3341d4b7a84292d8b9002a8095dd2382
    5022a69e45a073046a2b14b6a4e798910c920ee9
    We cannot bisect more!

Also noticed that \"git-annex-shell ...\" command succeeds if ran as root user, while failing from unprivileged one.
There are no permission/access errors in \"strace -f git-annex-shell ...\", so I guess it could be some bug in the GHC indeed.

JIC, logged a whole second bisect operation.

Bisect script I've used (git-annex-shell dies with error code 134 - SIGABRT on GHC error):
