When you run "gdb tellico" and tellico crashes, type "bt" without the quotes, to get a backtrace. If it has debug symbols (did you compile with CMAKE_BUILD_TYPE=debug?), that would help immensely. Thanks!

Yes I did compile with CMAKE_BUILD_TYPE=debug

(gdb) bt
#0  0x00007fffefa99788 in  () at /usr/lib/x86_64-linux-gnu/libQt5Core.so.5

I don't know if it will help but I also tried :

valgrind --tool=memcheck --leak-check=yes -v tellico |& tee -a valgrind_log.txt


Actually tellico did not freeze when it runs through valgrind.
[I closed the tip-of-the-day window, then selected a book, then File>Exit]

Thanx

Does 'bt' really only display a single line? We need the full backtrace. Please also install qt5 debug symbols, if possible.

Yes it does.
ASAP I'll try to install qt5 debug symbols and retry.
For now thanks.

So I've tried to install these:

    Development package (headers): qtbase5-dev
    Debugging symbols: qtbase5-dbg

but the latest one was not found, so I followed this guide:

https://askubuntu.com/questions/904451/what-happened-to-the-qtbase5-dbg-package-in-zesty

Then:

:~$ gdb tellico

That's all.

Hmmm. There's still no pointer into a crash inside Tellico. This is a bit weird. If we back up a bit, can you post the log file or output that you get when you run cmake? Thanks

before running cmake I've installed these missing libs:

catdoc
libepub0
libkf5filemetadata-bin
libkf5filemetadata-data
libkf5filemetadata-dev
libkf5filemetadata3

Does the backtrace really stop at #2? If there are additional lines, even incomplete ones, please show all of them. You might need to press Return to see more lines.

I hope now it will help

Your initial bug report had a lot of kdeinit5 errors. Do those still show up? I've been taking a stab at reproducing this or figuring out what's going on, so far without any luck.

I've put some crash guards in the code, though, mostly out of caution and guesses. Any chance you can grab the latest source code from kde git and recompile?

Created attachment 106673 [details]
gdb backtrace

same problem.
gdb backtrace in attachment.

Backtrace from comment #13 might be unrelated, because
1) its stacktrace points to models used in QTreeView, not in QListView,
2) it is probably caused by recursion from nested event loops from Tellico::EntryModel::data() calling Tellico::NetAccess::download().

maybe, so i should create separated ticket ?

If arrives the same for me using OpenSuse Leap-42.3
I'm able to launch Tellico but, as soon i click on his window, Tellico craches :-)

Installed ver. 3.0.2 from artful repo seems to work, despite Ubuntu version being different (I'm on 17.04)
IDK if I should put [SOLVED] because of the fresh install.

(Sorry but I couldn't follow the git-source suggestion)

But, again, I've lost bol.it support

(In reply to ghichtin from comment #17)
> But, again, I've lost bol.it support

Tellico 3.02 fixed the ibs.it search, but I don't think it has bol.it searching. Is that a different script that you have?

Yes I was referring to that one (ibs.it).
My bad.
But still, I don't have it.

I'm sorry, I'm not sure I understand the issue. It's not working for you? Or it's not showing up at all? If it's not in the data source list, can you verify that you have it enabled in the settings? If it's just not working, can you give me an example search to test?

There is not an ibs.it entry in Data Sources Options (Settings > Configure Tellico...) (and I don't know how to configure it)

With recent code changes to do asynchronous image loading, I believe this crash has been fixed.
