[pejakm]

@luke-jr In future please do not post a stacktrace like this. Enclose it in code or paste it on pastebin or somwhere and just paste the link here.

[JHooverman]

@luke-jr: Your issue refers to Qt-5.1, whereas your backtrace shows that Qt-4 is somehow involved (/usr/lib/qt4/libQtWebkit). Do you have a mix of two different Qt versions?

[luke-jr]

Correction: I have Qt 5.1 installed, but for some reason QupZilla built against 4.8.4. :(

[nowrep]

You must use qmake from Qt 5.

[luke-jr]

I don't see any way to do that.

[pejakm]

qmake-qt5?

[nowrep]

Or invoke it by full path to binary. (something like /opt/qt5/bin/qmake ?)

[luke-jr]

No such link. Apparently I have to use some non-standard PATH. :/

[nowrep]

Btw, are you using somehow big userstyle file?

[luke-jr]

No, none at all.

[nowrep]

I would say this is the same as #1044
So let's continue discussion there.
