[SOLVED] Texstudio segfaults after update

Hi together,

the last thing I did on Friday was to update and then I went into the weekend.

Today, I've tried to start Texstudio but I only get
>[1]    2293 segmentation fault (core dumped)  texstudio

Since I am sometimes a bit lazy with updating, I am not sure which packages got upgraded and therefore I am not sure which package I have to downgrade...

I hope you can help me :-)

You can read your log to see what was updated...

Moving to NC.

Re: [SOLVED] Texstudio segfaults after update

I have the same issue. I suspect the Qt 5.8 -> 5.9 update a few days ago which happened since the last time I was using TexStudio. The issue is a stack overflow while handling resize events:

Thread 1 "texstudio" received signal SIGSEGV, Segmentation fault.

I am sorry for just dumping this here. I currently don't have the time to investigate further / report it upstream, TexStudio broke in the worst possible moment (I am just using a text editor for now).

Why was this moved from the application forum, since this is clearly an application issue?

Edit: @kutkh The installation log can be found in 

/var/log/pacman.log

Re: [SOLVED] Texstudio segfaults after update

Thanks, I got it to work with the fix given in the upstream bug https://sourceforge.net/p/texstudio/bugs/2149/#75b5:

Chi-Hsuan Yen - 2017-05-06

Thanks for testing. I find the cause - my texstudio.ini has an invalid line:

centralVSplitterState=@ByteArray(\0\0\0\xff\0\0\0\x1\0\0\0\x2\0\0\x1\x84\0\0\x1\x17\0\xff\xff\xff\xff\x1\0\0\0\x2\0)

Removing this line brings texstudio back, even on Qt 5.9 beta 3.

Re: [SOLVED] Texstudio segfaults after update

Fixing texstudio.ini also solves the issue for me.

Thanks! :-)
