Description

I'm trying to run the buffer tool on a line and it keeps crashing Qgis. The line is created by merging two sets of gps point data and running points to lines with image_date as the order. I have no problem with it working on other data sets but for some reason there are two data sets that cause the buffer to crash the program.

There are quite a lot buffer tools in the Processing toolbox, which one you used? or you used a 3rd party plugin (among them also there are a lot of buffering tools).

In my case with the native QGIS tool, no crash, using 2.18.8 under Ubuntu, but is weirdly slow for such input.

Have you tried also a clean config, by wiping the .qgis2 folder (make a backup first)?

#2 Updated by timothy brink over 7 years ago

I'm using the native tool 2.14.11 and running a buffer of 7 meters. Anything I should worry about before wiping the qgis2 folder? I'd rather not go that route if possible.

make a backup/copy of it first, then you can restore.

It was easier to go in and edit the original gps file. I deleted the points where the gps sat still and drifted. It looks like there is a limitation on how many times the line can cross over itself.

Works fine in 2.18.9, tested Fixed and Variable distance buffer tool from Processing.
