Description

When creating a buffer shape file from certain shape layers, the program crashes if I have the option selected to dissolve the buffer. I was following instructions from the tutorial section 7.2.8 using the data from the source specified, and this worked fine for the roads layer. It also works if I perform the analysis without dissolve.

Note: The shapes generated without dissolve can then be merged into a single shape without any issues as a second step.

please attach the full datasets (the .shp file is not enough for a shapefile, you must also add the .shx, .dbf and .prj).

#3 Updated by Mark Thomas almost 4 years ago

The rest of the files are now attached.

you forgot to attach the original layer, the one where to apply the buffer.

#5 Updated by Mark Thomas almost 4 years ago

This should be the original layer, and all supporting files.

#6 Updated by Giovanni Manghi almost 4 years ago

no problems whatsoever here, at least on qgis master, Please give it a try and report back.
