Title: segfault when opening media network dialog box
Post by: mattkhan on February 10, 2016, 04:15:16 am: I now seem to have a mostly repeatable segfault in 21.0.39

steps to reproduce

- start MC
- open options
- open media network options
- media network is enabled
(segfault occurs at any point in these steps)
- click access key
- click test connection to server
- click ok on resulting dialog

here's a collection of errors that occur while testing the above

Haven't tried running with the debain testing distro.
I'd guess a library incompatibility.
You could try deleting your User Settings.ini file (of course you lose the settings) and see if that helps. Perhaps the stored window placement is messed up.
