[Bug 52131] wine-mono + RMS Express: HF Channel Selection Browser crashes

Alright, definitely confirmed that the crash is coming from some kind of
problem parsing small value frequency inputs.

First, I ran all of my 'made-up' grid squares but this time with a frequency
input of 7093000 (instead of 7093) and they all worked instead of all crashing
this time, so lat/long is definately not a problem (my made-up gridsquares go
over the entire map).

Then, I ran the same gridsquare with smaller and smaller frequencies until I
made RMS Express crash.
9W2RUT|AE01UB|709300|41|00-23|PUBLIC <-- working: "Freqs": [ 0.71]
9W2RUT|AE01UB|70930|41|00-23|PUBLIC <-- working: "Freqs": [ 0.07]
9W2RUT|AE01UB|7093|41|00-23|PUBLIC <-- crashes: "Freqs": [ 0.01]

Then, zero'd in on the minimum input frequency that RMS Express will accept
with wine-mono:

First sweep:
9W2RUT|AE01UB|70000|41|00-23|PUBLIC <-- working
9W2RUT|AE01UB|69999|41|00-23|PUBLIC <-- working
9W2RUT|AE01UB|60000|41|00-23|PUBLIC <-- working
9W2RUT|AE01UB|59999|41|00-23|PUBLIC <-- working: [STRING:032b56e8:AE01UB],
59.999000; "Freqs": [ 0.06]
9W2RUT|AE01UB|50000|41|00-23|PUBLIC <-- crashes: [STRING:032bb0a0:AE01UB],
50.000000; "Freqs": [ 0.05]
9W2RUT|AE01UB|40000|41|00-23|PUBLIC <-- crashes: "Freqs": [ 0.04]
9W2RUT|AE01UB|30000|41|00-23|PUBLIC <-- crashes: "Freqs": [ 0.03]
9W2RUT|AE01UB|20000|41|00-23|PUBLIC <-- crashes: "Freqs": [ 0.02]

Getting closer:
9W2RUT|AE01UB|59000|41|00-23|PUBLIC <-- working
9W2RUT|AE01UB|58000|41|00-23|PUBLIC <-- working
9W2RUT|AE01UB|57000|41|00-23|PUBLIC <-- working
9W2RUT|AE01UB|56000|41|00-23|PUBLIC <-- working
9W2RUT|AE01UB|55000|41|00-23|PUBLIC <-- working: [STRING:032818f8:AE01UB],
55.000000; "Freqs": [ 0.06]
9W2RUT|AE01UB|54000|41|00-23|PUBLIC <-- crashes: [STRING:03287bf0:AE01UB],
54.000000; "Freqs": [ 0.05]

Last test:
9W2RUT|AE01UB|54999|41|00-23|PUBLIC <-- crashes: [STRING:0323e768:AE01UB],
54.999000; "Freqs": [ 0.05]

So, RMS Express crashes with wine-mono when the input frequency for
PredictionClass.CreateDVOACapQuery is less than 55000
