These issues stem from Mono. I'm assuming this happened when trying to install Pinta, which depends on Mono. I thought I removed Pinta from the repository until the issue with Mono was resolved, but it must have been added again when I imported Debian updates.
Mono (and Pinta) are direct imports from Debian. I have not submitted a bug report to Debian yet. We could submit a bug report to Debian since Mono (and Pinta) are direct imports from them.
Or, we could try to build Mono from source (
build instructions). If the problem still occurs we could submit the bug report directly to Mono (
Mono Git Bug Report). They claim PowerPC is a supported platform (
Mono Supported Platforms).
It will probably be a few weeks before I have a chunk of time I can sit down and do all this.
If anyone wants to assist that would be fantastic.
