For "taskid:234" it matches ok:

py> re.search('^(taskid|bugid):\\d+',"taskid:1234")
<_sre.SRE_Match object at 0x00ACB1E0>
py> re.search('^(taskid|bugid):\\d+',"asdfa fa taskid:1234")
py> re.search('^(taskid|bugid):\\d+'," taskid:1234")
py> re.search('^(taskid|bugid):\\d+',"taskid:123adfa asfa lkjljlj")
<_sre.SRE_Match object at 0x00ACB8A0>

Because of the ^, it *only* matches at the start of the line. If you want  
a match anywhere (as implied by your error message), just remove the ^.
