Roku requesting wrong URL from HLS variant playlist

I have an m3u8 with the following format:

#EXTM3U
#UPLYNK-KEY:http://redacted.uplynk.com/ks/key?beam=2b74d2eade7d400faa4be161f7c407a8
#UPLYNK-MEDIA0:624x260x24,main-21,2x48000
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=644142

The expected behavior is that any of the bitrate streams can be requested at

http://redacted.uplynk.com/content/2b74d2eade7d400faa4be161f7c407a8/f.m3u8

for example. However, the Roku is making a request for

http://redacted.uplynk.com/content//content/2b74d2eade7d400faa4be161f7c407a8/f.m3u8

Here's a couple of (slightly modified, ip, hostname) log entries from our lighttpd access.log.

1.2.3.4 redacted.uplynk.com - [22/Feb/2011:04:47:42 +0000] "GET /content/2b74d2eade7d400faa4be161f7c407a8.m3u8 HTTP/1.1" 200 933 "-" "Roku/DVP-2.9 (012.09E01529A)"
1.2.3.4 redacted.uplynk.com - [22/Feb/2011:04:47:42 +0000] "GET /content//content/2b74d2eade7d400faa4be161f7c407a8/f.m3u8 HTTP/1.1" 500 15756 "-" "Roku/DVP-2.9 (012.09E01529A)"

Requesting any of the individual bitrate m3u8 URLs plays that particular bit rate fine.

Could someone verify the behavior, and suggest a solution/work around?
