It turns out this was caused by moreSecureMemoryForPinentry-qt.diff which in
(secmem/secmem.c) set.
--#define DEFAULT_POOLSIZE 16384
-+#define DEFAULT_POOLSIZE 16384*4
Removed patch and the problem disappeared.
Tue Nov 18 12:37:30 CET 2003 - mc@suse.de
- increase secmem allocation for pinentry-qt to avoid
"Out of memory" errors.
(pinentry-0.6.9.moreSecureMemoryForPinentry-qt.diff)
We no longer have qt (but qt4), a quick check showed no problems.
