Looks like the leak is in the IDLE handling:

poll(0x00090EB8, 2, 426)                        = 1
write(1, " *   S T A T U S   " P _".., 88)      = 88
poll(0x00090EB8, 1, 426)                        = 1
read(0, " 2 7 4   I D L E\r\n", 966)            = 10
open64("/home/gnb/Maildir/new", O_RDONLY)       = 142
fstat64(142, 0xFFBEF7D8)                        = 0
open64("/home/gnb/Maildir/cur", O_RDONLY)       = 143
fstat64(143, 0xFFBEF848)                        = 0
poll(0x00090EB8, 2, 421)                        = 1
write(1, " +   i d l i n g\r\n", 10)            = 10
poll(0x00090EB8, 1, 421)                        = 0
poll(0x00090EB8, 1, 0)                          = 0
