 Replying to [comment:19 mmetz]:
 > The most serious bug I am aware of was that cleaning would not work with
 the buffer column option, i.e. if different lines/areas are buffered with
 different distances. This has been fixed in v.buffer2, but the
 implementation in vbuffer2 is both using lots of memory and is very slow.

 support a buffer column with individual buffering distances and in order
 to handle some special cases.

 Just to make sure I understand: so your corrected version of v.buffer
 still contains a bug for buffer columns ? Any idea how this bug could be
 solved ? Or are you pleading for having a fast v.buffer without buffer
 column and maybe an option v.buffer.column based on v.buffer2 which
 provides a buffer column option, but runs slower ?
