[gst-devel] Could not close resource error when using gnomevfssrc with ftp

[Tiago Katcipis]

well it seems that is the same problem, i resolved to let the pipeline
"blocked" for a long time...and after something like 23min it happens the
same thing (Could not close resource.).

i run a full debugged launch and attached the part where the error occurs
(after 23 minutes).

gst-launch -v gnomevfssrc location=
ftp://194.44.214.3/pub/music/Collection/ArtofNoise.mp3 ! decodebin !
fakesink --gst-debug=5 2> no_queue.log
Setting pipeline to PAUSED ...
/GstPipeline:pipeline0/GstDecodeBin:decodebin0/GstTypeFindElement:typefind.GstPad:src:
caps = audio/x-wav
Pipeline is PREROLLING ...
ERROR: from element /GstPipeline:pipeline0/GstGnomeVFSSrc:gnomevfssrc0:
Could not close resource.
Additional debug info:
gstgnomevfssrc.c(889): gst_gnome_vfs_src_stop ():
/GstPipeline:pipeline0/GstGnomeVFSSrc:gnomevfssrc0:
Could not close vfs handle: Operation cancelled
Setting pipeline to NULL ...
/GstPipeline:pipeline0/GstDecodeBin:decodebin0/GstTypeFindElement:typefind.GstPad:src:
caps = NULL
Freeing pipeline ...

any hints if this is normal and i have to always use a queue after using a
vfs src element? maybe a bug on gnomevfssrc regarding an specific behaviour
of the ftp server?
