My Configuration:

  • A Lenovo T450s
  • Ubuntu 16.10 64bit
  • GNOME Shell 3.20.4

My Problem:

Sometimes suddenly and error pops up with 'Cancel' and 'Report problem` buttons. When I click on report problem this comes up:

enter image description here

Also, when I run dmesg I see this error line:

[ 1278.387019] evince-thumbnai[9012]: segfault at 50 ip 00007fd06dc0d940 sp 00007ffd97eecd98 error 4 in liblcms2.so.2.0.7[7fd06dbf9000+52000]

Any ideas how to fix or investigate the problem?

  • I'll start by submitting a bug against liblcms2 on Ubuntu bugzilla.
