I'm running simplyMEPIS (ubuntu-based) linux with the current version of wine. Wine runs some simple windows apps ok; however, when I run the dude (v. 2.2 and 3.x beta), it only makes it as far as letting me log in to the remote host 127.0.0.1 before crashing and closing. I see a few buttons on the left, as though the login were successful, then, suddenly, the crash. The dude then generates a little report that says "ACCESS VIOLATION" followed by a lengthy list of hexadecimal numbers.
Wasn't sure how to debug this. I ran WINEDEBUG using the relay channel per the advice of winehq.com, but the output appeared error-free, and incredibly verbose (the output file was 1GB!). I have another linux PC also with simplyMEPIS, and I see identical behavior on it.
I tried running winbox to see if the scope of the problem was limited to the dude. These PCs won't run winbox properly either - the window comes up, but there's no writing, even though the mstcorefonts package is installed.
Thought I would see if anybody has seen this. Mostly in these forums it looks like people successfully run dude+winbox on wine; alternatively I would consider running a different linux distro that people have had luck with in running the dude.
