[Bug 1826736] [NEW] Gimp crashes after Batch processing

 

Public bug reported:

Running Gimp under Ubuntu 19.04. I have installed gimp-plugin-registry
and using David's Batch Processor to open a group of .gif files and
export them as .png. After the conversion is complete, I hit the "Quit"
button on David's Batch Processor - and get this crash:

  New

Bug description:
  Running Gimp under Ubuntu 19.04. I have installed gimp-plugin-registry
  and using David's Batch Processor to open a group of .gif files and
  export them as .png. After the conversion is complete, I hit the
  "Quit" button on David's Batch Processor - and get this crash:
