Trac error: in permission list after adding the XML_RPC permission

[andy@…]

Hello there.

I have Trac 0.10.3 installed here, and after adding the XML_RPC permission to anonymous, "permission list" causes the following error:

Command failed: sequence item 0: expected string, list found

Meanwhile there is only anonymous with TRAC_ADMIN permission left, and the Trac Web UI gives me the following error:

Traceback (most recent call last):

I can't reproduce this issue neither with 0.10.3 nor 0.10.4:

I also tried with Python 2.4

Do you have any other plugin installed w/ your environment?

[anonymous]

Thanks for caring so far!

I installed the XmlRpcPlugin and the ExtendedXmlRpc-Plugin. Also the AzCalendarPlugin.

Try disabling the other plugins to see if the issue still shows up.
