$ gdb -p 3148

To weed out the obvious; I show that it is hung somewhere deep under:

QTextEngine::shapeTextWithHarfbuzzNG(
    QScriptItem const&, 
    unsigned short const*, 
    int, 
    QFontEngine*, 
    QVector const&, bool, bool
) const () 

from /opt/sourcetrail/lib/libQt5Gui.so.5

Hi @egberts, I think we fixes this issue some time ago. The Sourcetrail version 2017.2.0 is a little outdated by now, so can you please try to reproduce this issue with the latest version of Sourcetrail (which is 2017.4.21, it can be found here: https://www.sourcetrail.com/downloads).

[egberts]

Trying it now

Stuck in that loop for 8 days now? ;)

Looks like it's a closed issue now. Upgrade did the trick.
