[pmwiki-users] Small issue (related to ThumbList ?)

[ABClf]

Hello,

Using pmwiki 2.3.38, this seems to be an issue new to me (but might be older) :
on some page having a picture printed out with thumblist, I can read
this message :

Getting cache for Bob.12172, gallery-trail 1

repeated twice in a place it is not supposed to happen.

Something to do to fix it ?
Thank you,
Gilles
