Any application not listed here


Overall, not bad. Many of the referenced bug reports are paper cuts. None by itself breaks Trinity but all combined creates an uncomfortable feeling. :)

If somebody explains how to resolve the broken sym link bug reports, which breaks the HTML help files for non English languages, I am willing to work on resolving them.

Several of the other build related bugs are automake or cmake issues. I suspect most if not all can be resolved with nominal effort by experts.

I'll work with anybody who tackles any of the listed bug reports. I will patch, build, and test as fast as my dual core will allow me. :)
