ran today (11 January 2016 at 05:14 UTC+0) into a gui-runtime error:

* Read Configuration file: /etc/customizer.conf
X Error: BadAccess (attempt to access private resource denied) 10
  Extension:    130 (MIT-SHM)
  Minor opcode: 1 (X_ShmAttach)
  Resource id:  0x154
X Error: BadShmSeg (invalid shared segment parameter) 128
  Extension:    130 (MIT-SHM)
  Minor opcode: 3 (X_ShmPutImage)
  Resource id:  0x120000a
Etc.

Setting this is of help:

export QT_X11_NO_MITSHM=1

(System over here= Debian 4.3.0-1-amd64 #1 SMP Debian 4.3.3-5 (2016-01-04) x86_64, with gnome.)

Regards and thanks for the prog, I can archive a vew selfmade custom scripts.

This issue shall be closed for the following reasons:

1. This issue was already solved at the time of feedback, by workaround that user has mentioned.

2. This issue is similarly reported in other projects that depend on Qt; However, I have not been able to reproduce this issue on any host systems that I have tested so far (failed to reproduce issue).

3. There is no comment or response from other users to clarify this issue (failed to reproduce issue, lack of resources or information to reproduce issue).

This is now documented in Common issues on wiki and that shall be relevant all the time.
