Yes python is used by the lxml python pure xml parser. So adding and removing metadata and manifest properties for the cover would need to use lxml to parse the OPF for a sanity check both before reading and after writing for sanity.

My guess is this is not a general Sigil 2.8.6 issue but a Windows machine issue with limited stack space, limited memory, or limited file descriptors. For speed, gumbo can be invoked by QtConcurrent with multiple chapters being parsed at the same time. Ths can eat up open file descriptors like crazy.
