[plasmashell] [Bug 445327] New: Plasmashell crashes

https://bugs.kde.org/show_bug.cgi?id=445327

Bug ID: 445327
   Summary: Plasmashell crashes
   Product: plasmashell
   Version: master
  Platform: Debian stable
OS: Linux
Status: REPORTED
  Severity: normal
  Priority: NOR
 Component: general
  Assignee: k...@davidedmundson.co.uk
  Reporter: derp...@gmail.com
CC: plasma-b...@kde.org
  Target Milestone: 1.0

I have the problem that the control panel regularly disappears. Sometimes it
comes back on its own, sometimes I have to restart the Plasmashell process via
console. In the first case, I occasionally (not always) see the icon for a
crash report. However, it tells me that it is probably unusable because some
debug libraries are missing. I gave up trying to install them because I
couldn't find most of them in the Debian repo.


STEPS TO REPRODUCE
The problem usually occurs after changing the monitor setup, I often switch
between different docking stations. However, it doesn't happen right after the
change, but mostly after I've been working for a while. 

OBSERVED RESULT
Plasmahell crashes

EXPECTED RESULT
Plasmahell does not crash

[valgrind] [Bug 447386] New: Unhandled syscall on PPC32

[derplip]

https://bugs.kde.org/show_bug.cgi?id=447386

Bug ID: 447386
   Summary: Unhandled syscall on PPC32
   Product: valgrind
   Version: 3.15 SVN
  Platform: Other
OS: Linux
Status: REPORTED
  Severity: normal
  Priority: NOR
 Component: memcheck
  Assignee: jsew...@acm.org
  Reporter: derp...@gmail.com
  Target Milestone: ---

When I run my application with Valgrind on a 32 Bit PowerPC  platform I get
lots of these messages:

WARNING: unhandled ppc32-linux syscall: 407

The related name can be found in unistd_32.h:
#define __NR_clock_nanosleep_time64 407

Do I understand correctly that I have to write the appropriate handler myself?

--- Comment #3 from derplip  ---
I was not able to install 3.18 because of a Yocto/poky incompatibility, so I
chose 3.17. 
There is still one message: WARNING: unhandled ppc32-linux syscall: 325

Do you know if this is fixed in 3.18?
