ALG: Indeed in the styles part of the ODF there is svg:stroke-width="0,000pt" and svg:stroke-opacity="100,000%". The colon is the wrong sign here, it should be a point as numerical separator (AFAIK). Thus, the warning is correct.

So for the Inkscape export, it is an error in Inkscape. If I correct comma to dot, the file opens without warning.

But the other file still produces this error and has no decimal comma. It seems, that it is the special unit px, which does not work. Using pt for example gives no error.

ALG: So the question is, is px allowed in ODF? AFAIK it is no tallowed in the core, but that might be changed...

[ODF 1.2]
20.400 svg:stroke-width
"The svg:stroke-width attribute has the data type length 18.3.18."

18.3.18 length
"A (positive or negative) length, consisting of magnitude and unit, in conformance with the Units of Measure defined in §5.9.13 of [XSL]."

[URL see Bugzilla field]
5.9.13 Definitions of Units of Measure
The units of measure in this Recommendation have the following definitions:
Name	Definition
cm	See [ISO31]
mm	See [ISO31]
in	2.54cm
pt	1/72in
pc	12pt
px	See [5.9.13.1 Pixels]
em	See [5.9.7.2 Relative Lengths]

So yes, px is a valid unit in ODF.

ALG> Re-checked with patched file InkscapeSpirale.odg, exchanged commatas in svg:stroke-width="0.000pt" and svg:stroke-opacity="100.000%". After that, load cproduces no warnings.
I also checked conversion from pt to 100thMm done in SvXMLUnitConverter::convertMeasure in xmloff, looks correct. Nearly all units listed here are processed. Here are the exceptions:

- em is missing (started, but commented out)
- px is missing

Warning still there in AOO420m1(Build:9800)  -  Rev. 1614365
