Bug ID: 386859
Summary: KF5 KIO runs /usr/bin/kioslave instead of
/usr/libexec/kf5/kioslave, crashing the kdelibs3
kioslave
Product: frameworks-kio
Version: 5.40.0
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general
Assignee: fa...@kde.org
Reporter: kevin.kof...@chello.at
CC: kdelibs-b...@kde.org
Target Milestone: ---
This was originally reported downstream at Fedora:
https://bugzilla.redhat.com/show_bug.cgi?id=1512418
This code in KF5 KIO:
https://cgit.kde.org/kio.git/tree/src/core/slave.cpp?id=04147e26fa2c03584856693dddf7117d20f2ae6f#n507
introduced by this 2015 commit:
https://cgit.kde.org/kio.git/commit/src/core/slave.cpp?id=e2a4517f099d809bd53c6a10769ebfddc0f28a8b
makes KIO find the /usr/bin/kioslave executable if it exists (and prefer it to
the correct /usr/libexec/kf5/kioslave). Unfortunately, that is the executable
installed by the kdelibs3 compatibility package. As a result, the command line
that is run:
/usr/bin/kioslave /usr/lib64/qt5/plugins/kf5/kio/file.so file
obviously triggers a crash from mixed Qt/KDE libraries. (It is impossible to
run a KF5 KIO slave with the kdelibs3 kioslave binary.)
The:
<< QCoreApplication::applicationDirPath() // then look where our
application binary is located
line must be removed from the search path to prevent the crash.
