Bug ID: 394726
Summary: Discover freezes after searching for flatpak apps
Product: Discover
Version: 5.12.5
Platform: Neon Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: discover
Assignee: aleix...@kde.org
Reporter: yst...@posteo.net
Target Milestone: ---
Created attachment 112890
--> https://bugs.kde.org/attachment.cgi?id=112890&action=edit
Backtrace - search for 'ktorrent'
(If this does not belong in component discover please reassign).
**Problem**
Discover freezes and increases memory consumption (at one point it used ~5GB
before I killed it).
NOTE: My system has the flatpak-backend installed and a repository from flathub
(dl.flathub.org) – which Discover correctly recognises. System is KDE NEON
5.12.5. Qt 5.10
**Steps to reproduce (what I do that triggers this)**
– Launch Discover
– Immediately search for a flatpak app that is not installed – I search for
'keepass', 'zotero' and 'ktorrent'
– Choose the first result (which for me is a flatpak app of the search string)
– Sometimes I get to the app's info description, sometimes I don't – either way
Discover becomes unresponsive
The apps that freeze Discover come from flathub (keepassxc, zotero) and kdeapps
(ktorrent)
Reproducible most times.
I manage to reproduce this while launching Discover with GDB. Here are the
'backtraces':
When I search for 'keepass' and choose KeePassXC from the list gdb produces
thousands of these lines:
(process:12040): Snapd-WARNING **: Ignoring unexpected response
(process:12040): GLib-CRITICAL **: g_byte_array_remove_range: assertion 'index_
+ length <= array->len' failed
Attaching the others as text files if that's okay.
