[Bug 1450448] Re: kinfocenter crash

 

** Description changed:

- since the upgrade to 15.04 when you open kinfocenter in kde and click on open gl error the console output will say 
- $ kinfocenter 
+ since the upgrade to 15.04 when you open kinfocenter in kde and click on open gl you get an application crash - the console output will say
+ $ kinfocenter
  Failed to establish shared memory mapping, will fallback to private memory -- memory usage will increase
  kf5.kiconthemes: "Theme tree: (Breeze)"
  kf5.kservice.sycoca: Trying to open ksycoca from "/home/dave/.cache/ksycoca5"
  QObject::connect: No such signal QAction::triggered(Qt::MouseButtons,Qt::KeyboardModifiers)
  QObject::connect:  (sender name:   'search')
  Error: glXMakeCurrent failed
  
  the last line is of importance - after that kinfocenter crashes but
  doesnt close - it hangs ...

Title:
  kinfocenter crash

Status in xorg package in Ubuntu:
  New

Bug description:
  since the upgrade to 15.04 when you open kinfocenter in kde and click on open gl you get an application crash - the console output will say
  $ kinfocenter
  Failed to establish shared memory mapping, will fallback to private memory -- memory usage will increase
  kf5.kiconthemes: "Theme tree: (Breeze)"
  kf5.kservice.sycoca: Trying to open ksycoca from "/home/dave/.cache/ksycoca5"
  QObject::connect: No such signal QAction::triggered(Qt::MouseButtons,Qt::KeyboardModifiers)
  QObject::connect:  (sender name:   'search')
  Error: glXMakeCurrent failed

  the last line is of importance - after that kinfocenter crashes but
  doesnt close - it hangs ...
