crash due to an unhandled GEOSException

[msieczka]

QGIS trunk r9243, GEOS 3.0.0, QT 4.4.0, Debian testing amd64.

While zooming around my various data (shapefiles and an SRTM in the original hgt format) QGIS crashed out of sudden, saying in it's last lines of output:

fixed in r9244

Still crashes in r9245. Slightly different though:

I'm attaching a shapefile for testing.

a shapefile for testing

[telwertowski]

Not able to reproduce on a Mac. May be platform-specific or only occurs when zooming to a specific place in the file.

Added application-wide exception handler for uncaught events in r9319. It will display an alert rather than crashing and may allow you to continue working if the unsuccessful zoom hasn't left QGIS in an unstable state.

[mhugent]

Could you test if this bug is still valid and close if not? I tested with geos-2.2.3 and geos-3.0.0 and had no crash with both. There are a lot of warning about not closed linear rings on console, so my guess is that the geos exceptions are fixed now.

Replying to mhugent:

Could you test if this bug is still valid and close if not? I tested with geos-2.2.3 and geos-3.0.0 and had no crash with both.

I can't test, because the shapefile attached to this ticket is not visible now in QGIS. No matter what CRS I use for a project or the shapefile itself. What is it?

[pcav]

I confirm: the sample file loads without errors, but nothing is shown. On file (.dbf) of the three canonicals is missing.

[pcav]

Hi msieczka. It is unclear if the issue is still valid: the sample data are missing one of the necessary files (.dbf), so QGIS might be right not showing it. Could you please test again with valid data? Thanks.

[pcav]

Correction: the file does show up (you just have to zoom a lot). Zooming does not crash for me. Please reopen it if necessary.
