[amarok] [Bug 358804] amarok crashes at startup using pulse-gstreamer

2016-02-02 Thread via KDE Bugzilla 
https://bugs.kde.org/show_bug.cgi?id=358804

--- Comment #5 from bass...@hotmail.com ---
Hi,
Thanks again,

Behaviour changed a bit after rebuilding all dependencies with debug symbols
(not sure why), it used to crash at amarok startup, now it crashes when I hit
the play button after amarok shows up. In all cases, same behaviour:
gstreamer-0.10 is used at runtime. I am starting to suspect a version issue in
glib, or maybe this backtrace is not for the right thread?

Sorry for my misunderstanding about debug symbols.

stdout:

Well, you need to compile both Amarok AND its dependencies with debugging
enabled, because there still are no debugging symbols for the
phonon-backend-gstreamer, and the crash obviously happens there.

Hi,
Thanks for the answer.
I do not understand why symbols did not show up, I had them in KCrash before
sending the report...

About my CMake options, I am using Gentoo's portage build system, I did not use
fancy settings or anything. From what I see, only -DPHONON_BUILD_PHONON4QT5=ON
when building phonon-gstreamer, all others are defaulted. I double checked and
cmake finds gstreamer-1.0 at build time, but it really links to gstreamer-0.10
at runtime...

Here's the gdb bt of amarok-2.8.90 built from sources (2.8.0 gives the
samething):

Unfortunately you do not have debugging symbols, so the backtrace is pretty
useless.

FWIW: you should be able to use both 0.10 and 1.x versions, just make sure you
follow the compile instructions carefully, and of course you need the plugins
for both versions.

For the backtrace, please see
https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces
