Description squan 2010-07-24 00:11:12 UTC
Application: kget (2.4.4)
KDE Platform Version: 4.4.4 (KDE 4.4.4) "release 2"
Qt Version: 4.6.3
Operating System: Linux 2.6.34-12-default i686
Distribution: "openSUSE 11.3 (i586)"

-- Information about the crash:
A  download stuck at 57% (status "Stehengeblieben").
Because resuming was not possible I quit kget and restarted it.
The state was now shown as stopped ("Angehalten").
When trying to resume it kget crashed.
The crash was reproducable two times (two restarts).
On third restart kget completely forgot all its configuration settings and its download histor.y.


The crash can be reproduced every time.

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

Comment 1 squan 2010-07-24 10:53:55 UTC
It's a bit confusing for me but after another kget restart I found the download history properly restored.
The stuck download was still shown as cancelled ("Angehalten").

So I tried to restart the download from the browser.
This resulted in kget showing the usual popup to delete the incomplete file an to start over and at the same time continuing the stuck download!
I did not confirm the popup dialog.

Thus beside the crash I would consider the precedent stuck download situation a bug on its own.

The crash should not appear anymore with KDE 4.5.1.
Please create an own bug report for the issue of the stuck download, also detailing the url (if there are no privacy issues) if it happens often etc.
