skype Segmentation fault (core dumped)

dmgus · 06-30-2014, 06:22 AM

Ok, nevertheless skype 2 works quite stable, so we can name it a workaround

Thanks a lot!

they have skype-4.3.0 up there for the last few days, if you want to try that. I have it working here.

if it barfs, try it from inside a terminal, and post the exact output.
Just open an xterm and type 'skype'

Yes I've tried already and output is very usual:

Code:

$ skype

It could be memory.

I had a memory issue that I caught by doing LFS. The compiles would crash out occasionally. I could hit up arrow and return, and it would continue.

Skype is a 35Meg binary. It could be a memory issue.

dmgus · 09-03-2014, 01:46 AM

I still have this issue

Noticed interesting thing - I have segmentation fault even for Skype2 but don't have it for Skype2 with qt libs.
I.e. this won't work for me
https://aur.archlinux.org/packages/skype2/

But this works
https://aur.archlinux.org/packages/skype2-staticqt/

business_kid · 09-03-2014, 07:42 AM

Well, there is QT3 & QT4, and they are not compatible. I just seem to have qt4 installed (qt-4.8.2) with 64bit and 32bit libs (Alien Bob's stuff from slackware)

Last time I tried it all the graphics were fine, although sound is missing :-o. I never use skype; much less use it on a pc, but no segmentation fault.

dmgus · 09-04-2014, 04:00 AM

Ok, thanks for your hints, will try to dig further in QT direction. I hate ms, though forced to use their skype because of my clients

Before I had a workaround with skype 2.0 which worked fine though thanks to ms they don't support old versions anymore... So again no solution and need to fix it somehow

business_kid · 09-04-2014, 11:05 AM

Another thing to watch with qt is paths. There is a $QT_PLUGIN_PATH that skype recognizes (the readme in skype is fairly good at debugging various distros).
The usage is
QT_PLUGIN_PATH=/some/path skype

dmgus · 03-26-2015, 08:54 PM

Finally I've fixed it. After a recent system upgrade I was forced to remove lib32-icu and all dependent packages reinstall everything and skype works fine now.
