Application: plasma-desktop (4.11.11)
KDE Platform Version: 4.13.3
Qt Version: 4.8.6
Operating System: Linux 3.19.0-28-generic x86_64
Distribution: Ubuntu 14.04.3 LTS

-- Information about the crash:
- What I was doing when the application crashed:

Freshly installed Kubuntu 14.04 (64 bit) on Dell Latitude E6320 laptop.
Kernel: 3.19.0-28-generic
Phone: Samsung Galaxy S3 (GT-i9305) running MIUIv6, Android 4.4.4.

1. Connect Samsung Galaxy S3 (GT-i9305) with microUSB cable to the laptop
2. The whole plasma-desktop+kwin crash. I have to restart from command line

The crash can be reproduced every time.

Comment 2 Csaba Kertész 2015-09-16 07:24:21 UTC

An additional information for my previous comment: The plasma desktop crashes for me, regardless if the enabled/disabled USB debug option on the phone.

Comment 3 Csaba Kertész 2015-09-16 07:27:15 UTC

....and kwin does not crash always, only plasma-desktop.

Comment 4 Vishesh Handa 2015-10-29 11:16:46 UTC

Please upgrade to Plasma 5. KDE4 is no longer receiving updates.
