How to find out what program is trying to open the GNOME keyring?

Some tens of minutes after I login with a KDE session, I get a modal gcr-prompter window asking for the master password of the GNOME keyring. The prompt does not include any information about what program is trying to use the keyring or even if the prompter is started by gnome-keyring. From the security perspective, I find it kind of annoying that I need to enter an important password without even knowing which program is asking for the password. **Is there some way to find out which program requested access to the keyring?** The whole desktop is locked (all keystrokes go into the password field) and canceling several times cancels the whole prompt. On the Linux console I see the process started by gnome-keyring, but still I don't know which program is trying to open the keyring.
