Hello folks,

it's unfortunate that they use their own Gecko engine version *and* mshtml
browser embedding which pulls in Wine Gecko.

Wine: v4.10 of Netscape Portable Runtime
Yahoo Messenger: v4.8.3.0 of Netscape Portable Runtime

Two incompatible sets of runtime dlls are not supposed to be mapped into same
address space nor can be safely replaced by either provider.

If you replace the Yahoo provided one with the newer Wine Gecko runtime, you
can work around the missing 'nspr4.dll.PR_SetCurrentThreadName' entry point but
the Yahoo framework *relies* on unicode API present (MOZ_UNICODE).

Example:

Backtrace:

ret_addr=0x6128318e)

  3 0x60aaa7ac in ycpfoundation (+0xba7ab) (0x60a06cc0)
--- snip ---

Wine's Gecko obviously didn't have this compiled in.

But even then, you would need to replace the Yahoo provided runtime dlls with
what Wine provides at the risk of breaking the app relying on old API
behaviour.

IMHO a WONTFIX.
