Banshee.exe crashed with SIGABRT in g_cclosure_marshal_VOID__VOID() / while using Ubuntu 1 Store.

[TimSmith714]

I had searched for the band Skillet in the Ubuntu One Music store and clicked on the band name. I was going to scroll down the list of albums when the window greyed out and then disappeared

Status changed to 'Confirmed' because the bug affects multiple users.

[Andrea Cimitan (cimi)]

this is not a bug in overlay scrollbars, banshee is not using them!

[Jim Raredon (decoy-umd)]

This may not have anything to do with overlay scrollbars, but it's still a valid bug in banshee. Instead of just marking it invalid, please send it where it should go.

[Andrea Cimitan (cimi)]

right, I thought someone was doing that for me

i also get it if at the very first screen in the ubuntu one store scroll up & down

[Victor Pelt (victor-pelt)]

for clarity, i don't get it when scrolling in the amazon mp3 store opening screen. just for the ubuntu one store (something on the bottom of the screen that can't render?)

[Pedro Villavicencio (pedro)]

may someone on the ubuntuone team please have a look to it? thanks.

This is definitely an issue in WebKit. Something that changed in the 1.4.3 release broke it. Downgrading to the 1.4.2 release, packaged at https://launchpad.net/ubuntu/+source/webkit/1.4.2-0ubuntu1/+build/2620842 does not exhibit the problem.

[dobey (dobey)]

The crash in WebKit seems to happen as a result of embedding one WebView in a ScrolledWindow, later destroying that WebView, and replacing it with a secondary WebView, where the crash occurs. It seems like some memory is being corrupted internally in WebKit.

We can work around this in libubuntuone, so I am also assigning a task to it, which I will provide a fix for shortly.

[dobey (dobey)]

Also, it looks like this has been fixed in WebKit trunk already, but not yet backported. However, the patch does apply cleanly (minus the ChangeLog file of course). I'll prepare an update for that as well.

[dobey (dobey)]

Relevant fix from WebKit trunk: http://trac.webkit.org/changeset/95940/trunk/Source/WebKit/gtk/webkit/webkitwebview.cpp

[dobey (dobey)]

According to WebKit upstream, Empathy also exhibits this exact same crash, so perhaps best to get the webkit patch in, if we have to choose between it or libu1.

This bug was fixed in the package webkit - 1.4.3-0ubuntu3

[Victor Pelt (victor-pelt)]

it's fixed for me now

[Michael Terry (mterry)]

I pushed a libubuntuone to oneiric-proposed that purports to fix the libubuntuone side of this (not replacing webviews). Subscribing ubuntu-sru.

[Chris Halse Rogers (raof)]

Hello TimSmith714, or anyone else affected,

Accepted libubuntuone into oneiric-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

@TimSmith...

This sounds a little like bug# 778757 (https://bugs.launchpad.net/ubuntu/+source/ubuntuone-client/+bug/778757). Will tat one be addressed too? Hopefully ~ cause 778757 crashes the whole machine..

[dobey (dobey)]

Bug #778757 is a separate issue, and developers are working on it. As soon as a fix is available, we'll get it proposed for SRU as well.

[Chris Hermansen (c-hermansen)]

I retried this today (exactly what I originally posted) and had no problems Banshee 2.2 (2.2.0) standard Oneiric distribution. Not sure if proposed fixes have made it through since 27 October (today is 29 October).

Something else I should try? Otherwise I at least can mark the bug as fixed.

[dobey (dobey)]

Chris, the bug is already marked Fixed Relaesed. Please do not change any of the bug status fields. Thanks.

[Chris Hermansen (c-hermansen)]

Ok!
