[SOLVED] conky: Aborted (core dumped) after adding an execpi script

Hi,

I just added the following execpi line to my .conkyrc:

${execpi 1800 conkyForecastWU --template=~/.conkyForecast.template}

When I start it, conky correctly draws the output on my desktop but then - before refreshing it for the first time - conky stops with the following output:

Conky: desktop window (120006d) is subwindow of root window (ac)
Conky: drawing to desktop window
Conky: drawing to double buffer

The output of the given execpi command is as follows:

${font Raleway-10:weight=thin}

As said, it works for the first time, everything is visible on the desktop.

I already tried to save this output as text file and pass cat <path-to-file> as execpi command, but conky still aborted. So I assume it's a problem with conky itself and not with the conkyForecastWU-script.

Any idea what I could do?

By the way: I have this issue on two computers, both using MATE, conky Version 1.9.0, conkyForecastWU v2.24.

Re: [SOLVED] conky: Aborted (core dumped) after adding an execpi script

Ok, found some workarounds:

As shown in my first post, I used ${iconv_start}...${iconv_stop} because my ° degree symbols didn't look good. But I found out, that when I remove these iconv-commands from the output of the execpi command, I don't get a segfault anymore.

But yes, this ended with some broken °-symbols. So, I tried to find another workaround for this and voila! found one! After setting override_utf8_locale to yes, the degree symbols look good for me.

Even if my problems are fixed now, I think this should be reported as bug. So, if anyone from the conky team can hear me, read my post :-) I don't have the permission to create a bugreport for conky on sourceforge.
