2 years ago Looks like the crash is happening in the Qt Network module but you are missing debug symbols. Ubuntu Impish is using Qt 5.15.2 with a few patches, Qt 6 is not available on Ubuntu for some reason, no point in filing bug reports to Qt for 5.15.2. The Json output from the debug logging shows that one of the song is missing "duration" from the server so it's rejected, but I don't think that's related to the crash.

2 years ago Is the "use HTTP/2 when possible" in the Subsonic settings checked or unchecked? Can you try changing it and see if it makes any difference? Anyway, I think this needs to be reported to Ubuntu. Ubuntu is using the Qt 5.15 version which is no longer receiving patches from Qt for open source users, so it's a headache to deal with. they should be using Qt 5.12 LTS, Qt 6.2 LTS or the latest Qt 6 version which receives patches from Qt.

2 years ago I tested on Ubuntu 21.10 now and I can't reproduce any problems. What Subsonic settings do you use? Does it crash every time?

I just tried it on my other machine (also Ubuntu MATE) and it worked fine. Trying again on the machine where it crashed...

Still crashes on this machine. I've tried unchecking and checking the various options above, and it crashes every time.

2 years ago In case it's useful to anyone else, here is the (probably overkill) list of packages I had to install on Ubuntu 20.10 to build Strawberry:
sudo apt install \
libboost-dev \
libprotobuf-dev \
protobuf-compiler \
libalsaplayer-dev \
alsa-utils \
alsa \
libasound2-dev \
libsqlite3-dev libvlc-dev libcdio-dev libxcb1-dev libgstreamer1.0-dev \
libpulse-dev libchromaprint-dev libgpod-dev libmtp-dev libgdk-pixbuf2.0-dev \
kde-dev \
libkf5config-dev \
librust-gstreamer-audio-sys-dev \
libqt5x11extras5-dev \
libtaglib-cil-dev libfftw3-dev libgtest-dev \
taglib \
libtaglib*I built with:
git clone https://github.com/strawberrymusicplayer/strawberry
cd strawberry
mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Debug ..
make -j$(nproc)and ran with:
gdb ./strawberry
...
(gdb) rThen clicked "Refresh catalogue"

2 years ago This looks like a Qt bug. I suggest to install the debug symbols for qt5network and report this to ubuntu
