EMBOSS produces an error when doing wildcard searches

[Steiner, Guido {PRBT~Basel}]

Dear all,

has anybody else experienced problems when iterating over a database with a wildcard search?
For example, when I state
infoseq embl:\* , 
everything works as expected, but when I say
infoseq embl:p\* ,
after a while the output stops and the following error message is displayed:
  
 EMBOSS An error in ajseqdb.c at line 2550:
Cannot open sequence file 'em_in2_000.seq'

Of course this file exists and is not corrupted. Since other commands like seqret show the same behaviour, the problem
really seems to be in the ajax library.
Setup: EMBOSS 2.2.0 (64 bit build) on IRIX 6.5
from  uname -a:
IRIX64 rbaw20 6.5 10100655 IP27
from hinv:

Thanks for any help.
