Hi,
I have since some time problems to open some files in DT. I don't know if it is a DT or camera problem. When I remember correct it started after I upgraded both DT to 2.4.1 and firmware of my Nikon D5500.
This is what happens on console:
LANG= darktable
[rawspeed] (_DSC4981.NEF) void rawspeed::HuffmanTable::setCodeValues(const rawspeed::Buffer&), line 176: Corrupt Huffman. Code value 92 is bigger than 16
(darktable:12090): GLib-GObject-CRITICAL **: g_object_set_data: assertion 'G_IS_OBJECT (object)' failed
(darktable:12090): Gtk-CRITICAL **: gtk_widget_get_has_tooltip: assertion 'GTK_IS_WIDGET (widget)' failed
[rawspeed] (_DSC4988.NEF) void rawspeed::HuffmanTable::setCodeValues(const rawspeed::Buffer&), line 176: Corrupt Huffman. Code value 92 is bigger than 16
[temperature] failed to read camera white balance information from `_DSC4988.NEF'!
allocation failed???
On desktop, DT says it could not read white balance.
These files are already added to the database, importing the files was no problem. I think for the preview DT reads the embedded thumbnail. Problem is opening the raw data itself.
Distro is Gentoo. DT is 2.4.1.
But I tried recently DT on a Win10 64bit machine. At least one file made also problems.
I guess here are some problems.
The GTK messages appear independent of having buggy raw files. I don't know if this comes from GTK or DT. However I'm rebuilding x11-libs/gtk+-3.22.19 and then DT. Maybe that helps.
Then there are rawspeed/temperature errors. Since it only affects some raw files, I'd guess it is a ramdom bug in the raw files.
Is there a way of scanning a folder for such buggy raw files?
What can I do to fix these pictures?
How can I find out what the root cause of this is?
Best Regards, Micha.
