Assertion fails in nutils-of test

[Eder-K]

See https://travis-ci.org/github/precice/systemtests/jobs/742004326#L636. the openfoam participant crashes shortly after starting.

This error just started popping up, directly after the adapter was switched from using precice-ubuntu1804.home-develop to precice-ubuntu1804.package-develop.

This is the full message:

openfoam-adapter-outer    | ASSERTION FAILED
openfoam-adapter-outer    |   Location:          bool precice::xml::XMLTag::getBooleanAttributeValue(const string&) const
openfoam-adapter-outer    |   File:              /home/precice/precice/src/xml/XMLTag.cpp:133

and this is the origin:

https://github.com/precice/precice/blob/641e5057cb5d71d39ed43ae1dbc6af597b60bf52/src/xml/XMLTag.cpp#L133

Did anything change recently in the respective precice-config.xml?

[Eder-K]

Not on precice/tutorials, I can only assume this is entirely related to #256, which introduced the most recent change to the xml file:

systemtests/tests/TestCompose_nutils-of/Dockerfile.tutorial_data

Line 12 in 5a78292

s|\(\s\+\)\(</participant>\)|\1 <export:vtk directory="precice-output" />\n\1\2|g' \

Note that .home was unintentionally used instead of the intended .package image. This could explain why the error did not show up earlier.

I did find that the indentation of the inserted line was off by one space (the precice-config.xml for nutils-of uses a different indent size than other tests). However, this did not resolve the issue.
