Description

QGIS segfaults when I try to rightclick > "Save As" a JSON layer (geo- or topojson).

To reproduce:

1. Copy the example GeoJSON from http://geojson.org/ into a new file or use bl.ocks.org/mbostock/raw/4090846/us.json
2. Load that file in QGIS
3. Rightclick on the layer
4. Click on "Save As..."
5. QGIS will segfault

I tried with the latest GIT version at the time of writing. astrodog on IRC said it did not crash a version from some weeks ago for them. I attached a backtrace from gdb.

I assume you are using QGIS master, as you say "I tried with the latest GIT version at the time of writing", anyway I just tested on both Linux and Windows, with both QGIS 2.6.1 and master and the crash does not happen. Seems likely a local issue. Please try renaming the .qgis2 folder, (re)start qgis and try again. Cheers.

Yes, I meant a fresh checkout from git, sorry for not being clear. I used https://aur.archlinux.org/packages/qgis/ and made it not strip debug symbols. I am on 64 bit Archlinux.

It still crashes with a clean .qgis2. Same backtrace (apart from some different addresses).

it is not the first time that an arc user report such issues that are not replicable on other Linux distributions, especially debian/ubuntu. Maybe is something in your packaging.

It crashes in GDAL/OGR.
Can you open a bug report in their issue queue?
