[New-bugs-announce] [issue31559] IDLE: test_browser is failed when run twice

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

Buildbots failures:

http://buildbot.python.org/all/builders/x86%20Gentoo%20Refleaks%203.x/builds/101/steps/test/logs/stdio
http://buildbot.python.org/all/builders/AMD64%20Windows8.1%20Refleaks%203.x/builds/116/steps/test/logs/stdio

I don't know why test_browser fails first time, but this provokes running it second time why always fails.

$ ./python -m test -vuall -m test_browser test_idle test_idle
...
