Created attachment 1091 [details] Backtrace of segmentation fault When a message has a PDF attachment, I get consistent and reproduceable segmentation faults when I let claws (through the pdf_viewer plugin) display the PDF file. Opening the attachment through an external handler does not produce the segfault. I've attached a backtrace produced by gdb.
You should use the latest version of the plugin.
I thought I was, but apparently overlooked something. I have forcibly recompiled the plugin from scratch and the problem disappeared. Apologies for the noise.
