It would probably be worth testing both TE LSP's individually to check both
the LSP's are set-up correctly (Giles suggestion) and that there is not an
MTU issue on just one of the links (my thought).

the other possibility is broken forwarding in the LSP from the
destination back to the source.
"normal" traffic may be able to pop out of the tunnel and then be routed
hop-by-hop, whilst VPN traffic of course will be discarded as the
destination IPs are unknown at the core LSRs.
I have seen this in the past with TDP LSPs.
In fact the first thing to check is that there are LSPs in the reverse
direction ;-)
