It may be a linux only issue, but sometimes the search popup blocks the gui thread and monodevelop becomes unresponsive. I made some thread dumps of it:


I think that it looks like an infinite resize request loop.

should be fixed.
Comment 5 David Roth 2013-08-28 08:27:58 UTC
Nope, still freezing with latest fetch from github.
It freezes almost always If I enter a comma ',' following by a space ' '. Sometimes I have to repeat this a couple of times and then I run into the freeze.

May be a different problem - can you give me a kill -QUIT output ?

Which mono version are you using ?
Comment 7 David Roth 2013-08-28 09:27:01 UTC
Created attachment 4732 [details]

Sure, for the kill output see the attached file.
My mono version:

[mono-master] ~ @ mono --version

That's a mono 3.3 issue I think - I've problems with anything newer than 3.0.x on linux as well.

Can you try to go to 'main/build/bin' and start monodevelop with:

mono --gc=boehm MonoDevelop.exe

(but that's unrelated to the GetIdealSize fix - that's why it doesn't really help you :/)
Comment 9 David Roth 2013-08-29 02:35:00 UTC
with "mono --gc=boehm MonoDevelop.exe", MD also freezes, so no s-gen problem I think.
Do you know which part of mono is responsible then, so that i could fill up a proper bug?
Comment 10 Mike Krüger 2013-08-29 03:25:19 UTC
I think that's releated to an library - maybe gtk/gtk#

That's really hard to track down for us :/
