Bug#1081697: lsp-plugins-lv2: crash (segfault) when trying to import hydrogen drumkits (drumkit.xml)
Package: lsp-plugins-lv2
Version: 1.2.16-1
Severity: important
Dear Maintainer,
* What led up to the situation?
I'm using Ardour 8.6.0+ds-1+b1 and wanted to use lsp-plugin stereo
sampler from
package lsp-plugins-lv2 and import a Hydrogen drumkit into this plugin.
But
every tried drumkit lead to segfault of lsp-plugin and ardour.
I tried nearly every drumkit from the debian package, online library
download
and from a fedora instalaltion from another PC. but it crashed every
time.
On fedora 40 it worked without any problems
When I started ardour from command line I could read the following
output, when
tried to load drumkit:

It seems, that lsp-plugin sampler is unable to parse xml files

Perhaps, this could be the root cause...? lsp-plugins are built without
xml
support.
If this is the problem, please built lsp-plugins with xml support
Otherwise I would be happy to provide more information.
Thank you and best regards
Thomas
