[Christophe Dumez (hydr0g3n)]

the "X Error: BadDrawable (invalid Pixmap or Window parameter)" are odd but I don't think they are related to the crash.

Could you please use the following gdb command instead of "bt 25":
"thread apply all bt 25"

It seems that the crash is not in the current thread.

I have tried to reproduce but I couldn't.

It does not crash here on my Ubuntu v9.10 when saving a torrent to a NTFS partition... As a matter of fact, I don't have your X warnings either. This is strange, I'll try to investigate further the backtrace and warnings.

[Christophe Dumez (hydr0g3n)]

Your X errors could be Qt-related. Could you please try installing libqt4-dbg and get the all thread backtrace again?

[leftoflexo (beerpoweredhooligan)]

it does the exact same thing with the same errors on my fedora 12 X86. it happened directly after an update. it was working fine before the update.

[Christophe Dumez (hydr0g3n)]

Does the crash only happen when the main properties panel is displayed (the one with the downloaded pieces bar)?

Please try hiding the lower information panel (by clicking on the button that is currently highlighted and corresponding to the shown tab).

[Christophe Dumez (hydr0g3n)]

leftoflexo > Are you also downloading to NTFS?

[Christophe Dumez (hydr0g3n)]

Could anybody try this patch and tell me if it fixes the issue (I cannot reproduce myself but I may have found a possible cause for this)?

[Dmitry-Kogura (dmitry-kogura)]

Today, after update of libtorrent-rasterbar5, can't run qbittorrent 2.0.3
Message in terminal (Ubuntu 9.10):
qbittorrent: error while loading shared libraries: libtorrent-rasterbar.so.5: cannot open shared object file: No such file or directory

[Stamm (stamm)]

Sorry.
I have 2 not "100%" torrent, one of those save to ntfs, and I have 1 torrent, which allready downloaded, but check files (on ext3). Torrent which save to ntfs I was deleting, but qbittorrent still crash.
So, this situation about of cheching torrent, my sorry.

Now, I delete all torrent from qbittorrent and try to add this torrent - but qbittorrent again crash, but on start immediately.

"bad" torrent-file in attachment.

[Christophe Dumez (hydr0g3n)]

Dmitry-Kogura> qBittorrent v2.0.4 with the patch atatched to this report is being uploaded to my PPA. Please try apt-get update until you get the qBittorrent update.

[Christophe Dumez (hydr0g3n)]

Stamm > You torrent makes my qBittorrent crash too. This is good news, I can reproduce now: Thanks!

[Stamm (stamm)]

Christophe Dumez, by the way: I made this torrent with qbittorrent, but until i download from other torrent's site - everything was ok. I can attach this file if you need.

[Christophe Dumez (hydr0g3n)]

The problem is merely that the torrent is too big and qBittorrent cannot create a pixmap big enough to display the torrent pieces (hence the X errors). I'm currently addressing the issue, you should have a fix soon. Are you able to test patches if I attach one?

[Dmitry-Kogura (dmitry-kogura)]

Christophe Dumez: Thank you. Update to 2.0.4 has solved the problem.

[Christophe Dumez (hydr0g3n)]

The fix is committed to SVN. I'll attach the patch here so that you can test. I will release v2.0.5 with this patch as soon as someone confirms it fixes the issue.

[Christophe Dumez (hydr0g3n)]

Well, I have just released v2.0.5 with the patch. I hope it works for everybody. I chose to release fast because of New year's eve party :)

[Stamm (stamm)]

O, you are very quickly. This is a force of OpenSource!
I'm waiting for .deb for Ubuntu, I don't like make from source.
I try some GUI torrent programs(transmission, deluge, flush), but they have a problems
Transmission - very slow
Deluge try about year-two ago - don't like
Flush - don't correctly work with 2 and more trackers
You program - the best for me now ;)
Nearest to the future I want to create search plugin for qbittorrent for my tracker and I will recommend for use qbittorrent to linux-user.
Christophe, happy new year and big thanks for you program from Russia =)

[Christophe Dumez (hydr0g3n)]

Well, My PPA is up-to-date already for the .deb packages :)

[leigh123linux (leigh123linux-deactivatedaccount)]

Well I'm struggling trying to keep up with the new releases as Bodhi (fedora package release system) takes up to three days to process new builds :-(

[leigh123linux (leigh123linux-deactivatedaccount)]

I just managed to edit the 2.0.4 Bodhi request :cool:

[leftoflexo (beerpoweredhooligan)]

yeah i have mine set to save downloads to my downloads folder in my home which is a symlink to another ntfs drive. i went to download a rather large torrent, about 4.3 gigs. now after that i get the error above. i removed version 2.0.1 and installed 2.0.3 and it started with that error automatically which makes me think that there is some settings file left behind during the removal that the new installation picks up to continue the same error.
