All,
Before I forget, I see freezes with SVG when attempting to view in the embedded viewer in konqueror. (requiring the process be killed). It may be related to:
https://mirror.git.trinitydesktop.org/gitea/TDE/tdelibs/commit/ffe8e495d7e99...
Which fixed an svg icon issue. (I can see a -1 return for konqueror causing the lockup as well)
