Description

QGIS crashes on doing buffer on a polygon area that has been generated from open street map. The dataset has been extracted from the QGIS training manual in section 7.2.10 . I have tested this on windows and ubuntu 15.04, ubuntu 15.10. The version of QGIS is 2.12 and 2.10.

History

#1 Updated by Raymond Nijssen almost 10 years ago

While trying to replicate this bug some things were not clear to me. Paragraph 7.2.10 is describing an intersection and not a buffer. However, the previous paragraphs are about buffering, and the intersection uses a buffer layer as input. Could you please provide:

- a zip file with the vector data you try to buffer
- the function and input parameters you are using

Thank you!

  • Target version changed from Version 2.12 to Future Release - High Priority
  • Category changed from GUI to 44
  • Status changed from Open to Feedback

#3 Updated by Admire Nyakudya almost 10 years ago

The section I was referencing is the one in section 7.2.9 of the training manual. I have attached the screenshots of the commands Running qgis in the terminal results in a segmentation fault.

#4 Updated by Giovanni Manghi almost 10 years ago

  • Subject changed from QGIS crash on opening dataset in training manual to QGIS crashes when doing a buffer with ftools
  • Affected QGIS version changed from 2.12.0 to master
  • OS version deleted (15.04 ,15.10 and windows 7,10)
  • Operating System deleted (ubuntu and windows)
  • Status changed from Feedback to Open

Confirmed here on master.

The appeared after 2.8.3 (not sure if in 2.10 or 2.12).

#5 Updated by Alexander Bruy almost 10 years ago

There is no crash on master 5f3ca88 with fTools and Processing. fTools generates empty output layer, Processing throws error.
It is necessary to mention that provided layer has 2 geometry errors, this may be a root of problem.
