Description Henk 2015-04-04 15:19:33 UTC 
Application: baloo_file (5.6.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-12-generic x86_64
Distribution: Ubuntu Vivid Vervet (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
Installed GParted, and started it directly from Muon Discover application. 
GParted however seems to start normally, I could simply ignore the 'crash'

-- Backtrace:
Application: Baloo File (baloo_file), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Just had this crash while restarting docker service, just on another service. The crash is clearly in Solid.

Comment 11 Joshua Clayton 2016-08-02 22:16:06 UTC 
Situation:
partitioning an SD card from a script using parted.
Interestingly the new partition layout is usually the same as the old partition layout
I can crash plasma repeatedly with this trick. (thankfully plasma restarts)

Looks like soid tries to create a QVariant for something whose name is still valid, but
whose file handle has been destroyed.

Comment 34 Thomas Weissel 2016-11-30 19:47:24 UTC 
well.. i understand that starting gparted causes this crash and using parted from bash (my bug-duplicate) also crashes plasma.. 

but could it be possible that changing settings for a virtualbox vm also causes "the same" crash? (happens to me all the time..)  or should i report this somewhere else ?
Comment 35 Christoph Feck 2016-11-30 21:16:41 UTC 
Thomas, unless you are reporting crashes with a backtrace we have to consult the crystal ball...

Git commit 6f1c6dc84a3dbfc0b14946a52e84df49fc63f327 by David Edmundson.
Committed on 30/01/2017 at 12:15.
Pushed by davidedmundson into branch 'master'.

Work round DBus property fetching bug

Summary:
property() works in a slightly different way to just calling Get().
It allocates the variant of the relevant type in advance in QObject
code, and then calls
the DBus code to populate it.

This fails for QByteArrayList, before it reaches DBus code.
I don't know why, but we need a wokraround in Solid anyway.

>From a DBus traffic perspective this code is identical, we just avoid
going through Qt properties.

This shouldn't introduce any new bugs, as we already use GetAll
directly, if anything this brings it more
in line.

Test Plan:
Commented out the checkCache so that it always loads data.
Instead of failing, it now works.
