Bug#949035: blender: crashes when opening certain files
Hi,
there were multiple bugs or broken assumptions in Blender with the
given file, which appears to be a pre-2.5 file re-saved with 2.70.
Committed two fixes, the file should open fine now:
* https://developer.blender.org/rBd52551401e18
* https://developer.blender.org/rB3cd1c8ccffec
While the latter one could be back ported to the 2.82 release branch,
I'm not so keen on doing so with the former. We try to avoid
unnecessary risks at this point in the release cycle.
So don't expect the file to open fine in any 2.82 builds (although the
assert crashes should only happen in debug builds - with unknown
consequences for release builds). 2.83 builds should be fine, you can
test the nightly 2.83 alpha build once it's updated:
https://builder.blender.org/.
So I guess this report can be closed. Will leave that up to the Debian
team though, I don't know their policies :)
Cheers,
- Julian -
