Description Simon 2015-04-23 20:11:46 UTC
Application: plasmashell (5.2.95)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-15-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
I installed gparted and started it through a terminal with: kdesudo gparted
This made plasmashell crash, and unfortunately it's not reproducible. This may be a duplicate, but maybe the backtrace is still useful.

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

Comment 8 Rajeesh K V 2015-07-27 15:19:31 UTC
Solid::Backends::UDisks2::DeviceBackend::checkCache() does m_device->property(key.toUtf8()) at the crash site, where m_device is QDBusInterface and QObject::property(const char *) takes parameter char* instead of QByteArray - so, there seems to be a type mismatch.

But, shouldn't this crash happen everytime in that case? Also - can we convert the property name to char* as the property in question is "MountPoint" which I imagine can contain Unicode characters?

OK, so testing the interface

qdbus --literal --system org.freedesktop.UDisks2 /org/freedesktop/UDisks2/block_devices/sda1 org.freedesktop.DBus.Properties.Get org.freedesktop.UDisks2.Filesystem MountPoints
[Variant: [Argument: aay {{47, 98, 111, 111, 116, 0}}]]

(that's "/boot" in ascii, null terminated)

org.freedesktop.DBus.Properties.Get should always always return a variant  (see)
http://dbus.freedesktop.org/doc/dbus-specification.html

which we're getting here, and that variant contains the an object of type "aay" . All good there.

From the error we can tell that in qdbusmetaobject.cpp we're going into this path in 
QDBusMetaObjectGenerator::findType

       if (type == QVariant::Invalid || signature != QDBusMetaType::typeToSignature(type)) {
            // type is still unknown or doesn't match back to the signature that it
            // was expected to, so synthesize a fake type
            typeName = "QDBusRawType<0x" + signature.toHex() + ">*";
            type = registerComplexDBusType(typeName);
        }

Given udisks is already giving us a string in the most ridiculous way possible, it seems plausible that in some cases udisks is returning a property in the wrong format from the one they advertise in their interface.

Tried looking at udisks code, but I can't read this glib stuff.
Comment 11 David Edmundson 2015-07-27 20:44:36 UTC
Can someone reproduce this whilst running

dbus-monitor --system

?
Comment 12 bwucke+kdebugs 2015-08-07 15:30:01 UTC
Created attachment 93933 [details]
dbus-monitor --system log

As requested. It took me a few tries for it to occur, but eventually it happened, near the end of the log file. I had Firefox and Dolphin open at the time; I did access the volumes on the modem/pendrive before removing it ("unsafely"), then I reinserted it and Plasma crashed.

log above didn't have what I needed.

Can someone give me a reliable way to 100% reproduce this. Ideally with docker or some such.

https://bugs.kde.org/355476 has a bt generated when plasmashell crashed after starting docker. Hope it helps somehow.
Comment 27 David Edmundson 2015-12-04 16:39:58 UTC
I'm not after a backtrace, I want guided steps on making my system crash.
Comment 28 Anselmo L. S. Melo (anselmolsm) 2015-12-04 16:49:42 UTC
355476 was generated after a systemctl start docker.service

Comment 30 bwucke+kdebugs 2015-12-11 09:10:10 UTC
version bug#347641 - reproducible about 30% of the times. Steps to reproduce: insert modem, wait some 30s. If SD card reader and emulated DVD-ROM appear, the crash didn't occur, repeat.

It rarely takes more than three tries, and using the modem on the move, that's more than enough to make it very cumbersome... especially that after upgrade to Xenial, plasmashell often refuses to come back up after the crash, necessitating reboot.
Comment 31 bwucke+kdebugs 2016-01-15 18:20:35 UTC
It might be related to devices appearing, vanishing and reappearing in a very short sequence.
A recent update broke the automatic usb_modeswitch call from udev that had been switching the modem part on in my modem. Now I'm calling usb_modeswitch manually from shell whenever I plug the modem in, and the crash has not occurred even once since then. 

Normally, udev calls the modeswitch as soon as the device makes itself known. usb_modeswitch doesn't just enable the modem - it makes whole device with all its parts (modem, DVD, reader) reappear with a new product id. Manually, I can't call usb_modeswitch so fast after the device is recognized by the system without the modem.
