Thanks for your bug report. Please try to obtain a backtrace http://wiki.ubuntu.com/DebuggingProgramCrash and attach the file to the bug report. This will greatly help us in tracking down your problem.

[Juan Carlos Inostroza (jci)]

Bug confirmed in Feisty and Gutsy.

[Pedro Villavicencio (pedro)]

that trace is not really helpful, may you try again? please install the -dbg packages.

[Basilio Kublik (sourcercito)]

Sometimes i'm able to reproduce the bugs, sometimes no.
Anyway the gdb trace goes as atthachment.

[Basilio Kublik (sourcercito)]

what i meant before is that i can reproduce this bug sometimes, not every time.

[Emilio Pozuelo Monfort (pochu)]

I can't reproduce this with 1.4.2 under Gutsy.

Could you try installing it from http://ppa.launchpad.net/pochu/ubuntu/pool/main/l/liferea/ , and trying again?

Thanks
Emilio

[Pedro Villavicencio (pedro)]

Closing this report since no more information has been provided, feel free to re open it if you may install the package Emilio asked you for. thanks.

I have similar behaviour. Below is my liferea --debug-all. I think this is relevant to you, before this message the output seems not to have encountered errors.

.... (similar rows as the next one)....

UPDATE: trying to merge "Manovra, si' Commissione Bilancio" to node id "fhrjijc"
CACHE: check new item for merging: "Manovra, si' Commissione Bilancio"

Liferea did receive signal 11 (Segmentation fault).
You have propably triggered a program bug. I will now try to
create a backtrace which you can attach to any support requests.

Reopening.

[Emilio Pozuelo Monfort (pochu)]

Federico, what Ubuntu and Liferea release do you have?

[Federico Belvisi (armalite)]

I have Ubuntu Gutsy:

fritz@hyperion:~$ uname -a
Linux hyperion 2.6.22-14-generic #1 SMP Sun Oct 14 23:05:12 GMT 2007 i686 GNU/Linux

fritz@hyperion:~$ liferea --version
liferea 1.4.4

if you need more info just ask.

[Federico Belvisi (armalite)]

Some more info: I had to delete liferea.db and liferea.db-journal in order to have liferea working again. Also, crash occours during the automatic update feeds when liferea starts, so it is a little different from the original poster bug (who deletes the a feeds folder). I have a backup copy of liferea.db and the whole ~/.liferea-1.4 directory, if you need to investigate that.

[Emilio Pozuelo Monfort (pochu)]

Federico, if it's a different bug, please report a new one. Also, attach a backtrace (https://wiki.ubuntu.com/Backtrace) to it, and the steps to reproduce it (if possible).

Thanks.

[Emilio Pozuelo Monfort (pochu)]

Should be fixed in svn, to be released with 1.4.7
