Thanks.

Marco is this the same as the theme explorer crash?

Comment 2 Marco Martin 2015-03-30 15:57:16 UTC

David: don't think i seen this bt before (seen something somewhere related to a crash related to touch events tough)..
do you have a bug # for the explorer crash?

Comment 3 David Edmundson 2015-03-30 15:58:07 UTC

no, it's not been reported yet AFAIK.

Comment 5 David Edmundson 2015-04-07 22:52:49 UTC

Oh, I've found it!

QSGTexture::removeFromAtlas() returns a pointer but it keeps ownership of it.
Because I shove it in a QSharedPointer I delete it, then the original QSGTexture gets deleted and kills it too. 

I should either move the removeFromAtlas call into FrameNode, 
or for non atlased textures skip loading from the shared images cache.

Or both.

It's weird this is coming up at all, you'd have to request a pixmap from something that can be atlased, (icon, frame corner) then request the _same pixmap_ in a place where we don't have atlas's enabled. Clearly some theme is.

Git commit 33f651012b518ecf4970c549c7c4ab2ac7f1440e by David Edmundson.
Committed on 08/04/2015 at 09:15.
Pushed by davidedmundson into branch 'master'.

Fix crash in texture cache.

textures created by removedFromAtlas are owned by the parent texture,
they are not a copy.

Given this code should practically never be called, just create a new
texture object that manages itself and is not in the cache.

Fixed four months ago, but still crashes in Kubuntu ?
Could you take a closer look ?

Comment 20 Christoph Feck 2015-08-23 11:47:45 UTC

Tom, which frameworks version is installed in Kubuntu?

Comment 21 Tom Chiverton 2015-08-28 17:00:30 UTC

Seems to have been fixed at some point. Now I 4.14.8 installed (Kubuntu)
