We get lots if IDE crashes running on Linux (64 bit Fedora 21) - Many more than on the Mac version. Are there crash logs generated anywhere? We couldn’t get Feedback to install.

For your testing if you start it from a terminal then a fair amount of diagnostics are shown right in the terminal window
Any OS level crash logs should be where ever your install is putting them (assuming you get a core dump)
Feedback reports should be in ~/.Xojo.Feedback/Reports
Other applications write logs to /var/logs, but this folder does not contain any Xojo (or .Xojo) folder
~/.Xojo.Feedback/Reports is empty too.
