Hello,
I currently encounter the following error when using the robot framework plugin to publish our test results on jenkins.
This error does not always appear, but in about 7 times out of 10. In the other 3 cases, the result is published correctly.
I see this exact behavior on three different Windows 7 test machines. The generated .xml and .html files appear to be ok. Is there any possibility getting around that problem?

Output: D:\dev\Jenkins\workspace\jst-tst\output.xml
Log: D:\dev\Jenkins\workspace\jst-tst\log.html
Report: D:\dev\Jenkins\workspace\jst-tst\report.html
