Description Erik Sohns 2021-01-15 22:07:41 UTC 
this is the relevant stacktrace: (type contains a NULL so "type.get()->" doesn't work)

~"#0  binaryurp::Unmarshal::readValue(com::sun::star::uno::TypeDescription const&) (this=0x7fffe67fa860, type=...) at /usr/src/debug/libreoffice-7.0.4.2-3.fc33.x86_64/binaryurp/source/unmarshal.cxx:249\n"

any ideas ?
Comment 1 Julien Nabet 2021-01-16 09:04:05 UTC 
It could be useful to have minimum step by step process to reproduce this.
Comment 2 Erik Sohns 2021-01-16 10:03:38 UTC 
this is already a minimal setup. I use XComponentLoader::loadComponentFromURL() and cast the result to sheet::XSpreadSheetDocument. I assert that the cast works with the .is() method(s). i.e.

component_ = component_loader_p->loadComponentFromURL()
assert (component_.is ());
document_.set (component_, uno::UNO_QUERY);
assert (document_.is ());
spreadsheets_p = document_->getSheets (); // <<-- SIGSEGV

this is the minimal code to reproduce the error
Comment 4 Erik Sohns 2021-02-12 18:31:44 UTC 
I found the solution myself. I was not setting the environment/ini variables UNO_TYPES and UNO_SERVICES correctly, so the bootstrap wasn't working
