Qt Creator crashes when editing a .ui file

Description:

Qt Creator crashes after a few minutes of editing a UI file. This also appears to happen with Qt Designer as well. At some point before it crashes, it prints out the following, though this may or may not be related:

Failed to initialize instances shared memory:  "QSharedMemory::handle: doesn't exist"
QFSFileEngine::open: No file name specified

Additional info:

  • package version(s): 13.0.1-2
  • config and/or log files: N/A
  • link to upstream bug report, if any: N/A, this does not happen with upstream Qt Creator

Steps to reproduce:

  1. Open Qt Creator
  2. Create new widgets project or open a current one
  3. Open and edit .ui file
  4. After a few minutes, it will crash with a segmentation fault
