Description bob.dicarat 2011-05-13 08:56:31 UTC
Application: kget (2.6.2)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-9-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
When I star Kget, the program goes completely wild, starts a few wild downloads randomly chosen from ktorrent downloads anf finally crashes. The result is my directories getting filled with files that are called like prevoiously ktorretn downloads, that occupy drive space, don't work and if used makes the whole system stall. Crazy!

The crash can be reproduced every time.

-- Backtrace:
Application: KGet (kget), signal: Segmentation fault

Comment 1 Matthias Fuchs 2011-05-13 09:02:37 UTC
So the downloads it started weren't in KGet before but only in KTorrent?
Comment 2 bob.dicarat 2011-05-13 12:14:14 UTC
yes Matthias, they where only in Ktorrent. Thanx for your interest.

Lukas

Comment 6 Matthias Fuchs 2011-05-16 11:11:23 UTC

Comment 8 Lukas Appelhans 2011-05-20 13:00:51 UTC
At the moment I can't think of any reason why KGet should pick up any KTorrrent downloads...

Lukas
Comment 9 bob.dicarat 2011-05-20 15:26:47 UTC
Well thanks for trying. For the moment I switched to another download
manager but I will try later on to check if a newer version will work again.
By the way, just in case you wondered, I tried several times to remove and
reinstall with no success. So for the the moment it will stay removed.
Thank you

Comment 10 Matthias Fuchs 2011-05-21 14:22:20 UTC
I tried to reproduce this issue running Kubuntu 11.4 in Virtualbox but I was not able to. Not sure if the app data (~/.kde4/share/apps/ and there kget and ktorrent) and their settings ~/.kde4/share/config there the corrent settings) of KGet and KTorrent could help.
Comment 11 bob.dicarat 2011-05-30 00:48:24 UTC
i don't quite get what you mean or are asking for,,,, do you want me to  
send you my settings?

Comment 12 Lukas Appelhans 2011-05-30 10:48:54 UTC
Yeah, please post them!

I really have no clue how this could theoretically happen, but maybe the settings will give us a clue!

Lukas
Comment 13 Matthias Fuchs 2011-08-04 16:40:55 UTC
As mentioned we can't imagine how this possibly could happen. So your settings might give us a clue or maybe even a way to reproduce this issue.
In fact if you have any personal information in there make sure to remove it.
Comment 14 bob.dicarat 2011-08-06 06:38:43 UTC
Dear Matthias,

I'm no expert and have really no idea of what kind of info I should send
you. As for me, I simply removed Kget and lived happily ever since. But if
it can be of any help or interest for you, let me know exactly the kind of
info you need. I'd be glad to help even though i doubt that I will turn back
to Kget.

All the best and thanks for your interest.

Bob

First thing would be to make sure that you can reproduce this issue.

The files that could be useful for us are the kgetrc file from ~/.kde4/share/config then the transfers.kgt file from ~/.kde4/share/apps/kget

Then on the KTorrent part ~/.kde4/share/ktorrent/log also ~/.kde4/share/config/ktorrentrc

Make sure that these files do not contain any information you do not wanna see on the internet though.
