Re: [LAU] qtractor crashes (was: the defacto host for lv2)

One possibility is that totally independent of Qtractor, an installed
faulty ladspa calf plugin is messing things up... I've removed the
offending "ladspa-calf-plugins.x86_64 0.0.18.5-3.fc12."
(Perhaps this is ultimately the plugin that was causing the other
errors I was seeing when browsing different plugin dirs in qtractor,
earlier?)

Is there any way of isolating a plugin host from faulty plugins like
this? Especially when they're just there and not even being used.

I will see (and follow up on) whether qtractor ends up working more
stably without the bad plugin.
Removing the plugin stops rosegarden from crashing, for example:

Ogetbil for the suggestion
https://bugzilla.redhat.com/show_bug.cgi?id=600713#c3 ):

Indeed, after removing ladspa-calf-plugins, it [rosegarden] now quits
with a warning, but
doesn't coredump. I will await update of this package. Thanks for letting me
know of this interaction, especially on a plugin I'm not using but is just
"sitting" in the directory. That level of sensitivity to faulty plugins is
therefore the bug for this particular crash. It'll be interesting if that also
clears up the qtractor issues also pointing towards memory corruption, which
happen infrequently.
