$ grep gtk_recent vim71/src/*.c | wc -l
0

There is no use of GtkRecentManager in the vim source.

Yet using strace on vim reveals this

[...]
open("/home/gber/.recently-used.xbel.WBHYEU", O_RDWR|O_CREAT|O_EXCL, 0666) = 15
fcntl(15, F_GETFL)                      = 0x8002 (flags O_RDWR|O_LARGEFILE)
fstat(15, {st_mode=S_IFREG|0644, st_size=0, ...}) = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fcbd288f000
lseek(15, 0, SEEK_CUR)                  = 0
write(15, "<?xml version=\"1.0\" encoding=\"UT"..., 218) = 218
close(15)                               = 0
munmap(0x7fcbd288f000, 4096)            = 0
rename("/home/gber/.recently-used.xbel.WBHYEU", "/home/gber/.recently-used.xbel") = 0
stat("/home/gber/.recently-used.xbel", {st_mode=S_IFREG|0644, st_size=218, ...}) = 0
[...]

on every keypress, mouseclick etc.

Me neither, so what is happening here?
