#1416: crash querying very small GRASS vector polygon
---------------------------------------------------------+------------------
Reporter: msieczka | Owner: nobody
Type: bug | Status: new
Priority: critical: causes crash or data corruption | Milestone: Version 1.0.0
Component: GRASS | Version: HEAD
Keywords: | Platform_version:
Platform: Debian | Must_fix: Yes
Status_info: 0 |
---------------------------------------------------------+------------------
amd64 Debian testing, QT 4.4.3, QGIS trunk r9668
I have a very small polygon in my GRASS vector map. If I try to query it
with identify tool when
it's veray small on my screen (few pixels, hardly visible) QGIS crashes as
below. No crash if I zoom close enough to see the polygon fill and then
query.
