Python crashes when running mach test

[TileHalo]

Hi!
When i run $ ./mach run tests/html/about-mozilla.html It prints following

ERROR:script::parse::html: Parse error: Unexpected token Error running mach:

['run', 'tests/html/about-mozilla.html']

The error occurred in code that was called by the mach command. This is either
a bug in the called code itself or in the way that mach is calling it.

You should consider filing a bug for this issue.

If filing a bug, please include the full output of mach, including this error
message.

The details of the failure are as follows:

CalledProcessError: Command '[u'target/servo', 'tests/html/about-mozilla.html']' returned non-zero exit status -11

File "/home/leo/code/job/mozilla/servo/python/servo/post_build_commands.py", line 26, in run
env=self.build_env())
File "/usr/lib/python2.7/subprocess.py", line 540, in check_call
raise CalledProcessError(retcode, cmd)

(edit) I pulled and now it says this. It was also the original message, but it printed the odd one once

Did you succeed to build first?

[TileHalo]

Yes.

[jdm]

Any difference if you use target/servo tests/html/about-mozilla.html instead?

Issue #3867 seems to tell what happens. Im also running Arch Linux.

Same error here, also Arch Linux. https://gist.github.com/agilob/aac801fd3bcba48743db

:: ~/Projects/servo ‹master› » ./target/servo tests/html/about-mozilla.html
ERROR:script::parse::html: Parse error: Unexpected token
[1]    13269 segmentation fault (core dumped)  ./target/servo tests/html/about-mozilla.html

How can I help you debug it?

[jdm]

gdb --args target/servo tests/html/about-mozilla.html
(gdb) run
(gdb) backtrace

And paste the result here, please :)

Window wasn't closed after SEGFAULT, I had to kill application

[jdm]

Looks like #3867 as well. Whee.

[agilob]

It works here.

[jdm]

Great!
