Do you refer to the "zonal statistics" core plugin (c++) or its counterpart in the QGIS Processing toolbox?

I cannot replicate the issue with any of my data, can you please attach sample data that cause the issue? thanks.

#2 Updated by Sergio Antonio almost 5 years ago

This zip file contains a clip of srtm_27_17.tif, two polygon grids (shp) created by vector grid tool (10000 x 10000 m and 1000 x 1000m), and the zonalstatistics.qgs.
All of them in EPSG 31983 - SIRGAS 2000 / UTM zone 23S.
I refer to the "zonal statistics" in the QGIS Processing toolbox.

no error here with your project and dataset. What version of Processing are you using (check the version in the plugin manager)?

still no error here. Tested on Linux and Windows. Seems likely a local issue, would you mind testing on a different system?

that is a message that is thrown by SAGA, not QGIS (is anyway not important apparently).

#6 Updated by Sergio Antonio almost 5 years ago

The error happens in three machines (Windows) that had version 2.6 and were upgraded to 2.8 and, then, to 2.10.
Ok, it seems that really isn't a bug. I have discussed it with others users that, like you, didn't find the error.

I would suggest try (backup and) delete the .qgis2 folder and try again.

#8 Updated by Sergio Antonio almost 5 years ago

I deleted the .qgis2 folder, then I removed qgis 2.8 and I restarted the machine: sorry, the problem remains.
I verified that this machine had the versions: Brighton, Chugiak, Wien and Lisboa.

so you have machines where this error always surface but you know that does not happen on other users machines (like mine)... what the machines where the bug occur have in common? XP?

#10 Updated by Sergio Antonio almost 5 years ago

Yes, XP.
Just now I prepared, for testing, a fourth computer that was out of use (Windows XP) and the error occurred again.
Those machines do not accept others versions of Windows. I believe that they are gone finally...

#11 Updated by Sergio Antonio almost 5 years ago

Please, can I consider that the bug is just a XP/QGIS incompatibility and close the updates?

#12 Updated by Sergio Antonio almost 5 years ago

A new machine (Intel® Core™ i7) is running with Windows 10 and the problem persists.
