On Friday night, we upgraded our imapd server's hardware & OS to Solaris
10 from Solaris 8.  Both machines are running UW imap 2007f.  We
recompiled it on the new machine.

As our users come back, we're seeing some log messages

Jan 27 10:38:40 HHHHH imapd[8566]: [ID 273760 mail.alert] Fatal error
user=XXXXXX host=XXXXXXX.AI.SRI.COM [NNN.NNN.NNN.NNN]
mbx=/path/to/a/mail/folder: impossible empty keyword
Jan 27 10:38:40 HHHHH imapd[8566]: [ID 746981 mail.alert] IMAP toolkit
crash: impossible empty keyword

I don't yet know how many mail folders are impacted by this.  I don't
know what triggers these errors (no one has complained yet)

I see this error message in mix.c (our mail is stored as mix mail
folders), but I haven't yet looked to see what the code is doing (but I
will).
If someone else has run into this issue and can shed any light, please
let me know.

Are you running on a ZFS store? There was/is a bug I found that was activated by using an undocumented feature of the stat() function to do some preallocation. It is fixed in the "Panda" release, NFI if it ever made it back into UW-IMAP.
