Bug#750590: gnuplot-x11: Crashes with wxt terminal

[Thorsten Bonow]

Package: gnuplot-x11
Version: 4.6.5-3
Severity: important

Dear Maintainer,

gnuplot crashes when the terminal is set to 'wxt' with the output
attached below. Setting the terminal to 'x11' works.

The bug appears to have been introduced in 4.6.5.2, which shows the same
behaviour. Downgrading to 

	   gnuplot_4.6.5-1_all.deb
	   gnuplot-doc_4.6.5-1_all.deb
	   gnuplot-x11_4.6.5-1_i386.deb

fixed the problem for me.

Best regards,

Toto
