When reading mail and pressing s for saving mail pine shows SAVE Msg #27 to folder [foldername]: and waits for input. When the proposed foldername already exists everything works fine. New folders are ignored. If you enter the same foldername when asked and do not just press return to accept the proposal the folder is created. Pressing enter to accept the proposal does not work. (the glibc2.2 update is installed)
And PIne 4.30-2 was used. 4.21 worked fine.
This bug is fixed in PINE 4.31 which is yet to be released soon.
Actually, I have just recently put PINE 4.32 packages into RAWHIDE. The 4.32 release adds many bugfixes, and I suggest either: 1) Try the rawhide release 2) Wait until I release an errata of PINE 4.32 for 7.0 (no ETA).
