Qtractor doesn't open in Librazik-2 (SOLVED)

12 May, 2019 - 15:45 — briandc

Hi all,
using 32-bit Librazik-2 here.
I'm not sure if it's due to a recent package update, or conflict with new installed packages, or something else..
Previously I just got a "segmentation fault."
So I re-installed Qtractor, and now I get this:

re. Qtractor doesn't open in Librazik-2

sorry, I have no clue what is going wrong but it looks like you're having trouble with some, one or more plugins of an existing session and it crashes when opening it, right?

you can take several routes to find which one is the culprit, if not qtractor itself:

a. run qtractor under gdb and take a full symbolic backtrace that will pin-point to the thread or spot where it is having the segfault;
b. start a new session from scratch, starting clean and try adding the same plugins as you know are in the faulty session (from the dump above you have a serious bunch of lv2's, dssi's and ladspa's as list of suspects); save and re-open the session one step at a time until it chokes in similar way as the one at stake;
c. also in an iterative manner as previous one, edit the xml on a copy of the session file (.qtr) and start cutting one plugin entry at a time, until the session loads cleanly;

i really think you'll probably have to go with a (re)mix of the above until the nasty bugger is found.
sorry for the mess: remember to backup and more importantly ALWAYS have trials with working copies, never with the originals ;)

hth.
cheers

Hi rncbc and thanks for the tips.
Before I begin testing as you recommend, I ought to mention that Qtractor was in fact the first application that I opened after QJackCtl. No synths, effects, nothing. I had no other apps open at the time, and no previous Qtractor sessions to load either. It was a "clean" opening, so to speak.
Perhaps if I uninstall the recent plugins, it will clear things up...

Finally got a chance to look into this. I tried removing the "naspro-bridges" package, and voilà! Qtractor works again! :)
Thank you, rncbc, for your suggestions.

Hopefully this will be useful to others using Librazik2! :)
