Description
I am trying to validate a few geometry layers using Processing/QGIS geoalgorithms/Vector geometry tools/Check validity and it immediately fails each time I try with the following message.
-2147483645 See log for more details
The processing log contains the following:
Uncaught error while executing algorithm
Traceback (most recent call last):
File "C:/OSGEO4~1/apps/qgis-dev/./python/plugins\\processing\\core\\GeoAlgorithm.py", line 203, in execute

KeyError: -2147483645
It doesn't matter if I select either QGIS or GEOS as method in the parameters. Of course this also affects the QGIS menu/Vector/Geometry Tools/Check Validity.

I forgot to mention, that it works fine in QGIS 2.16.1.

Your shapefile contains 2.5D. QGIS master now by default saves Processing outputs into memory layes, which does not support 2.5D geometries.
As workaround you can save algorithm results to file.

if this is fine in 2.16...can we close the issue? Looks like a limitation in QGIS < 2.16 with memory layers, as Alex says, so there is nothing we can do to fix that

Well I think if you are going to close this ticket, shouldn't the user be made aware of why they get this error message? I mean something like "The input data 2.5D geometry and processing can only save to file and not memory layer. Please select an output file." or similar?
At least until memory layers are capable of handling 2.5D geometries.

I tried not setting a file for valid output (and uncheck the "open output file after running algorithm"), and two shape files for invalid and error output. I get two error messages with the same large negative number for each.
If I set a file for each of the three outputs it seems to work.
So I guess that the "open output file after running algorithm" doesn't suppress the creation of a memory layer. I would expect it to completely skip the memory layer, if the user doesn't want to open it afterwards, since it is the same as putting the results directly into the waste bin.
