Thanks for the reproducible test case.

I've forwarded this bugreport to the upstream issue tracker to help get
the segfault resolved. I'm downgrading the severity to important because
this issue because it doesn't render the package completely unusable to
everyone.

I don't have systems with GDAL 1.11 at hand any more, but with GDAL
1.10.1 on jessie your command still fails with the same error messages,
ogr2ogr just doesn't segfault:

$ ogr2ogr -a_srs WGS84 -f GeoJSON -where "ID=098530" \
-nln "098530" p098530.json argos.xml ; echo $?
ERROR 1: Type mismatch or improper type of arguments to = operator.
FAILURE: SetAttributeFilter(ID=098530) on layer 'argos_trip' failed.
1

Because the ID column is of type String, you should quote the value to
not have it interpreted as an integer:

$ ogr2ogr -a_srs WGS84 -f GeoJSON -where "ID='098530'" \
-nln "098530" p098530.json argos.xml ; echo $?
0

This doesn't trigger the type mismatch error and SetAttributeFilter()
failure, and the subsequent segfault (which should not happen either way).

Kind Regards,

Bas
