    For some unknown reason DVcsJob->exec() or something around this place trashes memory when "hg" is launched. Basically if you run MercurialPlugin::status or any other (like MercurialPlugin::commit) several times then can see that something is overwriting some parts of memory as program doesn't exit cleanly but with segfault. Atleast I noticed this for unit test app. It might be either DVcsJob bug or hg bug, because if I changed job to any other executable (eg. git) it worked fine.
