Bug Hanging on adb (Android) process when entering play mode

Basically these bugs:

• http://issuetracker.unity3d.com/iss...editor-starts-to-hang-when-trying-to-close-it
• http://issuetracker.unity3d.com/iss...-for-the-first-time-also-launches-adb-dot-exe

Happening here on Kubuntu 15.04 even when editor is set to build for Linux (not Android)

 

I was having this happen as well. When starting Play Mode currently for the first time after launch I normally have to launch a terminal and run "adb kill-server" then run "adb devices"(or similar to start the the process again). One odd thing is the first "adb devices" command if performed quickly tends to trigger a adb process launch failure then the second seems fine.

I also don't know what started this issue as mine was working fine without doing this for weeks. Then I started messing around with Unity Remote and built one Android application, so I'm not exactly sure which of these triggered the issue initially.
