I have a project with reprojection active. If I "zoom out" enough I can make qgis crash. The bug is reproducible on my machine.

The following error messages are left in the console:

Can you please provide more details? Does this happen with every layer, or just one? Raster or vector? Any projection, or a specific one? Please try to simplify your project as much as possible while still getting the crash, so it will be easier to reproduce it (currently I can't). Thanks.

#2 Updated by Giovanni Manghi almost 15 years ago

Not reproducible here with qgis 1.2 from trunk under Ubuntu 9.04, not even hitting very fast on the "zoom out" button or the mouse wheel.

Please give it a try again and report back.

#3 Updated by Giovanni Manghi over 14 years ago

  • Resolution set to worksforme
  • Status changed from Open to Closed

Tested again on qgis 1.1 and seems to work fine. Closing, but please reopen if necessary.
