Yes, there is a second Lucid user reporting the exact same problem. The thing is it looks like a weird dependency problem and not an actual bug (it does not crash in my code).

I tried to install Lucid and reproduce but I couldn't. Does this happen for all torrents?

Yeap.. crashes are on any torrent file.
Even on my private torrent files, that I did in the qbittorrent, a few days ago.

eMcE: Check please a qBittorrent in your paragraph: "Pre-allocate space for all files" if ext is enabled, try disabling it and add the torrent again.

Ok, I can reproduce it but only on Lucid and only if preallocation mode is enabled. I have no idea yet of the cause but I'm looking into it. Please disable preallocation mode in the mean time.

Without preallocation works ok.

I have found the problem. This was caused by a bug in qBittorrent, introduced in v2.6.0.

I have just uploaded the following package with the fix to my PPA:
qbittorrent_2.6.2+svn.r5072

Please confirm that this fixes the issue for all of you.

Changed in qbittorrent:
importance: Undecided → High
milestone: none → 2.6.3
status: Confirmed → Fix Committed

@Leigh: You are probably interested in that patch. The bug is basically that I write in a place in memory where I shouldn't when full allocation mode is enabled. The side effects are impossible to predict but it is likely to cause strange crashes like it does on Ubuntu Lucid.

The patch will be in v2.6.3 but I'll probably wait a few days before I make another release (too many releases recently).
